Field assessment

Strengths

S2 adds block and self-recovery in a persistent stance with a fast opening.

Limitations

S2 reduces reach and defense. Flying enemies and pressure outside his tile need another answer.

Upgrade advice

S2 unlocks at E1 and is already functional there. Consider S2 mastery if he is regularly your first laneholder.

Common questions about Mountain

Which Mountain skill should I use for laneholding?

Use S2, Sweeping Stance. Activate it after deployment to gain self-recovery and hit the enemies he blocks. The stance trades away his normal reach and some defense.

When does Mountain need backup?

Bring ranged coverage for drones and an Arts attacker for enemies whose defense prevents him from clearing the lane. His self-healing is most useful when damage comes at a pace he can sustain.
