Golem Lord Argelmach

The Manufactory
Clear the workshop before approaching Argelmach's rear room. Bring golem pulls back into the cleared entrance rather than fighting beside another workshop pack. Establish control of Argelmach's accompanying constructs before spreading out for Chain Lightning; the workshop's eastern route continues to the Grim Guzzler.

Golem Lord Argelmach
Elite HumanoidArgelmach combines Chain Lightning that grows stronger as it jumps with a Lightning Shield that punishes attackers.
Abilities

Chain Lightning
Strikes an enemy with a lightning bolt that arcs to another nearby enemy. The spell affects up to 5 targets, inflicting greater Nature damage to each successive target.
Spread out and interrupt Chain Lightning before it jumps into progressively stronger hits.

Lightning Shield
Remove Lightning Shield with enemy-magic removal if available; its retaliation can hit ranged attackers as well as melee.

Shock
Instantly throws a bolt of lightning at an enemy, inflicting Nature damage.
Keep the current victim healthy for Shock while the group is already taking lightning damage.
Tank- Clear the workshop before pulling Argelmach and establish control of his accompanying constructs. Leave enough room for the party to separate for Chain Lightning.
Healer- Stand apart from other casters so Chain Lightning cannot use the ranged group as successive jump targets. Watch attackers who take Lightning Shield retaliation as well as the tank.
Damage- Assign a Chain Lightning interrupt and spread out. Remove Lightning Shield if you can dispel enemy magic, and finish the accompanying constructs without clustering the whole party beside Argelmach.
