According to Grim Dawn’s lore, the Demolitionist is a class that are part engineer and part sorcerer. They are effective when it comes to explosions. This hybrid mastery is proficient in dealing both physical and magical damage by laying traps, throwing grenades, and putting any kind of pyrotechnics into its attacks.

Note: Recommended Devotions are not in order here. It is up to you on what constellation you should learn first. Devotion points can also be re-assigned in order to meet certain requirements.

When it comes to gear components, resistance to different damage types should be the priority for your character to survive on higher difficulties.

Thanks Marlock. That helped a lot. I was super confused why the devotions weren't matching up.

Quill

Scholar's Light

Ghoul (assign celestial power skill to Flame Touched)

Hydra

Magi (assign celestial power to one of the Inquisitor's passive skills)

Owl

Rhowan's Crown (assign celestial power to Fire Strike)

Chariot of the Dead (assign to Aura of Conviction)
