Game plan by role
Kog'Maw · Bot
Coordinate trades with your support and keep last hits consistent. Stand where you can attack without stepping into both enemy players’ threat range.
Collect safe farm while staying close enough to join your team. Check the map before crossing an exposed side lane for one more wave.
Keep dealing damage to an accessible target while tracking enemy engage tools. A safer sustained position is often better than chasing a distant carry.
Before your next fight, check: Caustic Spittle · Living Artillery · Combos
Kog'Maw · Mid
Use the wave to control when trades happen. Keep a defensive option if the opposing jungler is missing, and avoid forcing a combo into a large enemy wave.
Move after checking the wave, vision and who can follow. A useful roam should not cost several uncontested waves for no clear opportunity.
Fight from a position where you can repeat your useful spells. Look for an opening after enemy control is spent instead of entering first by habit.
Before your next fight, check: Caustic Spittle · Living Artillery · Combos
06
Matchup preparation
Compare opponents in the build for the role you are actually playing. Then check their key control, escape and defensive spells before choosing your trade.
07
Practice checklist
- Cast each ability alone and identify its range, target conditions and stopping point.
- Practise the first sequence slowly. Repeat it while moving, without skipping the conditions shown on its card.
- After each attempt, identify the spell you would still have available to defend or retreat.
