Guide
Play as a poke-heavy caster in ranged form, then all-in with hammer form when enemies are low. Prioritize positioning and gate placement to control teamfights.
Tips
Use your ranged form to poke and stack Manamune efficiently before all-ins.
Switch to hammer form to finish off low-health enemies with your burst combo.
Place your Acceleration Gate (E) to help your team engage or disengage in narrow ARAM lanes.
Buy early armor penetration items like Serylda's Grudge to maximize damage against squishy targets.
Save your melee E (Thundering Blow) to peel for yourself or knock back divers.
Combos
Ranged Q (Shock Blast) through E (Acceleration Gate) for long-range poke.
Ranged W (Hyper Charge) + auto attacks for quick burst, then switch to melee Q (To the Skies!) to gap close.
Melee Q (To the Skies!) + auto + melee W (Lightning Field) + melee E (Thundering Blow) for a full burst combo.
