Expert Tips
- Switch forms constantly — Hammer form gap closes and slows, Cannon form pokes from range. Never be in one form too long.
- Your level 3 all-in (E-Q in hammer → switch → Q-E cannon poke) is your kill window if ahead.
- Build items that synergize with both forms — Eclipse or Trinity Force are optimal core items.
