易大師 Strengths and Weaknesses

When Ahead

• Take over the fight only after the first layer of danger is gone. If the enemy has already spent their main stun, knock-up, or peel on your front line, go in immediately. That is your trigger. Use Snowball or a side angle to enter on the back line, not through the center. The reason is simple: ahead Yi wins by chaining kills, and you only get that chain when the target cannot answer you cleanly. If you jump first into full CC, you waste the lead and give them a free reset window.
• Play like a finisher, not a starter. Stay just outside the front of the fight until someone drops to a level where one clean commit can break the fight open. Then cut through the back line, force a panic flash, and keep moving. The consequence of this style is that the enemy cannot stabilize once you get one takedown. If you overchase the first target into the enemy formation, you can still throw the fight even while ahead, so finish the kill and immediately look for the next safe angle instead of tunneling.
• Use your lead to deny counterplay, not to dive blind. If the enemy carry is isolated, low mobility, or already forced to step forward, punish that lane of space right away. If they stay grouped with layered peel, wait for them to break formation or for your team to create crossfire. Ahead Yi should make the enemy choose between losing the carry or losing the fight. The punish window is when they turn to save one target and expose another.
• Augments that add durability or sticking power matter more than pure greed when you are already winning. If you pick up an augment that helps you survive burst, cleanse pressure, or stay attached to a target, you can walk deeper before you become killable. If you get an augment that boosts damage while you stay in combat, it lets you convert one kill into the next one faster. Those augments cover your biggest weakness ahead: getting overconfident and dying before the cleanup starts. The practical result is fewer shutdowns and fewer fights that slip away after a strong opener.
• Look for snowball angles that start behind the enemy line or from fogged space. If you can hit a target without showing your path early, do it. If the enemy sees you crossing open ground, they will pre-aim the CC and force you to burn your exit too early. Hidden approach is your reward for being ahead. The counterplay is simple: if they stack vision and peel tightly, stop forcing the same route and wait for a wider angle.
• Do not trade your life for the first carry unless it ends the fight. When ahead, the trap is greed. If you go too deep and die after getting one kill while your team is still healthy, you can turn a winning position into a coinflip. Your recovery plan is to reset your target selection: back out if the back line is fully protected, then re-enter once the enemy front line turns or your team repositions. A small pause is better than handing over shutdown value.
• Let your team start the brawl if they have reliable engage. If your allies can lock people down, hold your entry until the crowd control lands. That gives you a clean punish window and forces the enemy to spend their escape tools on the first wave instead of on you. The consequence is a much safer chain fight, because Yi ahead is strongest when the enemy team is already disorganized.

When Behind

• Stop treating every fight like a dive angle. If you are behind, your trigger is different: wait until both teams are committed and health bars are already thin. Enter only when you see a near-dead target, a missed key spell, or a gap in peel. That is the only kind of fight you want. If you jump in early, you become the cleanest target on the map and the enemy gets to erase you before you can contribute.
• Play for cleanup, not for hero plays. Behind Yi still threatens fights, but only when the enemy has already used enough resources to make their back line fragile. Stay patient, hug the edge, and force the enemy to overextend into your team before you commit. The reason is that your damage pattern is still dangerous, but your margin for error is gone. One bad entry can make the game unrecoverable, especially if the enemy has multiple forms of crowd control or burst.
• Use Snowball as a test, not a promise. If you throw Snowball and the target has clear peel behind them, do not blindly follow just because it connects. Use it to check whether the enemy has already spent the answers you care about. If they still have hard CC ready, cancel the fantasy and wait. The punishment for forcing it is usually instant death, and behind Yi cannot afford that trade.
• Augments should patch your survival before they chase greed. If you are behind, the best augments are the ones that help you live through the first burst, move through the fight cleanly, or keep you relevant without needing a perfect opening. Damage-only augments are much weaker if you never survive long enough to use them. Defensive or utility augments cover the exact hole that being behind creates: you need one more second to get to the cleanup stage. That extra second is often the difference between a lost fight and a comeback kill chain.
• Do not front-load your resources into a low-value target. If the enemy tank is healthy and the carry is fully protected, back off. Your job is not to prove you can hit the nearest body. Your job is to wait for the enemy to overstep, separate, or burn their protection first. The consequence of tunnel vision is that you spend all your threat on a target that the enemy already expected you to hit.
• Pick fights around enemy mistakes, not around your cooldowns. If the enemy carry steps too far forward, if a peel spell misses, or if your team lands a knock-up or stun, that is your opening. Otherwise, keep circling. When you are behind, patience is part of the kit. The recovery plan is to survive the first wave, then punish the next mistake. That is much safer than gambling on a full commit into fresh enemy cooldowns.
• Keep your death timer value in mind. If your team is already low and the enemy can end off one lost fight, do not force a risky commit just because you found a half-open target. Sometimes the correct play is to show presence, draw attention, and let the rest of your team reposition. Behind Yi can still change the fight by threatening the flank, even without fully diving. If the enemy respects that threat, your team gets breathing room. If they ignore it, you get a clean punish window later.
• Never burn every escape and engage tool at once unless you are sure the fight ends there. If you blow Snowball, ultimate, and your angle all at the same time, you lose any room to recover when the target survives or gets peeled. Behind, you need a second plan. Hold one layer of entry if possible so you can disengage or re-enter after the first exchange. That single reserve is what keeps a bad fight from becoming a total collapse.

Bottom line: when ahead, Yi should force the enemy to panic and then punish the crack in their formation. When behind, he should slow down, wait for chaos, and only clean up after the enemy has already spent the tools that kill him. The whole game is about timing your entry. Enter too early and you throw. Enter on the right pause and you can still flip the fight.
