Grock

Grock gains a shield equal to 14% <1005> and empowers the next Basic Attack to deal 4 (+2% Total Physical Defense)% target's <1005> Physical Damage (capped at 300 (+20*Hero Level) against non-hero units). Cooldown: 18s - 12s (decreases with level). This cooldown is reduced by 200% when near terrain.
Grock's skills cannot be interrupted, and he gains 30 (+6*Hero Level)% extra <1060> while the shield is active.

Grock strikes forward with massive force, dealing 240 (+100% Extra Physical Attack) Physical Damage. Enemies with obstacles behind them are knocked back into the obstacle, knocked airborne, and take 4 (+2% Total Physical Defense)% <1005> extra Physical Damage (capped at 300 (+20*Hero Level) against non-hero units). If there are no obstacles behind, enemies are only knocked back slightly.

After a brief delay, Grock summons a stone wall in the target area, dealing 100 (+60% Extra Physical Attack) Physical Damage and knocking enemies towards him.
Use Again: Cancel the wall early.

Grock charges forward and gains Control Immunity, dealing 100 (+50% Total Physical Attack) Physical Damage to enemies in his path. Upon hitting terrain, he immediately stops and triggers a massive explosion that knocks nearby enemies airborne for 1s and deals 650 (+300% Total Physical Attack) Physical Damage. If this skill doesn't hit terrain, 50% of its cooldown is refunded.
