Guide
Play as a disruptive tank-engage, using your E to initiate fights and your passive blobs to sustain through poke. Focus on peeling for carries with Q and R, and build tank items to survive extended brawls.
Tips
Use your E to engage from fog of war or over walls for surprise initiations.
Collect your passive blobs in ARAM to sustain through poke and stay in fights longer.
Maximize your Q's slow by hitting two enemies or a minion and a champion for a double stun.
Build Spirit Visage early if the enemy team has heavy magic damage to boost your healing.
Coordinate your ultimate with team crowd control to knock enemies back into your team.
Combos
E > Q (on two targets) > W > R to engage, stun, and disrupt.
