Mars
Force a fight in a chosen area and give allies a clear target inside Arena of Blood.
First check
Where will Spear of Mars push the target, and can your allies reach the arena?
Play as Mars
- Use lane positioning to create a useful Spear angle before committing. A target pinned in reach of your partner is better than a flashy hit alone.
- Before Arena of Blood, check allied arrival and the enemy heroes outside the wall. A contained target still needs follow-up damage.
- After the arena ends, move the nearest wave and take the objective your catch opened instead of chasing a scattered survivor.
Play against Mars
- Do not bunch beside a wall or tree when Mars is missing. Give Spear fewer easy pinning angles.
- Keep a save or damage dealer outside his likely Arena of Blood so the team has a response after he commits.
- When his major initiation is unavailable, pressure the next wave or objective before his team can set up another fight.
Make the lesson stick
Pause before three arenas and mark the spear destination, allies in range to follow, and enemies left free outside.
