Terrain tank whose combo gets far stronger next to a wall
TankFighterRoamEXP LaneDeals physical
Grock is a roam or exp tank whose entire combo scales up around terrain. Mighty Swing knocks enemies into obstacles for a bonus airborne effect, Earthen Rampart summons a wall that blocks escapes or splits the enemy team, and Tectonic Charge explodes for massive extra damage and a cooldown refund if it hits a wall.

Strengths
Mighty Swing knocks enemies into terrain for a bonus airborne effect and extra damage tied to his Physical Defense
Control Immunity while casting skills makes him hard to interrupt mid-combo
Tectonic Charge deals a much bigger explosion and refunds half its cooldown if it hits terrain
Earthen Rampart's wall can block enemy escape routes or split the enemy team mid-fight
Weaknesses
Most of his combo needs terrain nearby to reach full value — in open areas his CC is much weaker
Earthen Rampart has a telegraphed delay before it lands, giving alert enemies time to reposition
His empowered basic and Mighty Swing's bonus damage scale off his own Physical Defense, needing specific itemization
Tectonic Charge only refunds cooldown if it hits terrain, so missing it in the open is a costly whiff
Skills
Max Mighty Swing first for damage and CC uptime, then Earthen Rampart for the wall and zoning, taking the ultimate at 4, 8 and 12.
Passive
Bastion of Stone
Buff
Grock gains a Shield equal to 10% of his Max HP and empowers the next Basic Attack to deal Physical Damage equal to 4 (+2% Total Physical Defense)% of the target's Max HP (capped at 300 (+20 × Hero Level) against non-hero units). This effect has a 18-12 seconds cooldown (decreases with level), which reduces by 200% when near terrain. Grock gains Control Immunity while casting skills and 30 (+4 × Hero Level)% extra Physical Defense while the Shield is active.
Always active — no cooldown

Terrain Engage Tank
7,300g total
Default pick when Grock is the team's primary engage.
The 'Flicker combo' — blinking in right as a hook or stun lands, or blinking out the instant an enemy ultimate is cast — is the single most common high-elo outplay moment in the game.
Swap in when needed
Antique Cuirass — Against physical skill-combo fighters punishing his engage.
Athena's Shield — Against a burst magic diver he has to engage into first.
Immortality — Insurance for committing hard to a terrain-based engage.
Grock Terrain Engage Tank build: Tough Boots, then Brute Force Breastplate, then Dominance Ice, then Guardian Helmet.
EXP Bruiser
7,540g total
When laning top and needing to hold the wave and duel alone.
Petrify's short stun window is enough to force a follow-up teammate combo but not to solo-lock a target — pair it with an ally's burst rather than expecting to win the fight alone.
Swap in when needed
Radiant Armor — Against sustained magic damage in extended lane trades.
Immortality — Insurance for over-extending in a solo lane.
Grock EXP Bruiser build: Warrior Boots, then Brute Force Breastplate, then Queen's Wings, then Guardian Helmet.
Who counters Grock
The heroes that make this matchup hard, and the mechanic that does it.
Line up Mighty Swing so the target has terrain behind them for the bonus airborne knockback
2
Use Earthen Rampart to wall off a chokepoint and split the enemy team before committing to an engage
3
Aim Tectonic Charge to end against a wall — the terrain explosion is where the real damage and knockup is
4
Build Physical Defense early since it directly scales his empowered basic attack and Mighty Swing's bonus damage
Grock — common questions
Is Grock good for beginners?
Grock is moderately beginner-friendly — his skills are simple to fire off, but getting real value out of them means learning to read the map and set up terrain, which takes practice.
What is the best build for Grock?
Tough Boots into Brute Force Breastplate, Dominance Ice and Guardian Helmet covers the standard engage-tank build, adjusting into more magic or physical defense depending on the enemy composition.
Which heroes counter Grock?
Esmeralda is the hardest counter since Frostmoon Shield siphons his own Bastion of Stone shield and her damage ignores shields outright, while Alice, Uranus, Natalia, Joy, Claude, Valentina, Chip and Khaleed all dodge or outlast his terrain combo in softer ways.
What does Grock's ultimate do?
Tectonic Charge sends Grock charging forward, dealing physical damage along the way, and if he hits terrain he stops and triggers a large explosion that knocks nearby enemies airborne for a full second.
