The Magus: Craft Focuses I

From publisher blurb:

These subclasses were made for the Magus class.

The pack includes three new craft focuses for the Magus. The Arcane Duelist is based in increasing the durability of the Magus in combat, and allowing their spells to be consistently damaging to opponents. Clockwork Magecraft allows the Magus to store spells within gears, generate ether points from spell slots and to create a variety of gear on the spot for them and their allies. The trickster is an assassin-like Magus who can deal extra damage in opportune situations, weaken opponents and strike move around battle more quickly.
