This is crazy useful! It details and explains the mechanics of SWADE Core Summon Ally, then goes to break it down to allow GMs and players to easily make their own allies, plus providing additional Edges and Hindrances for summon-centric characters. Examples of new allies of all Ranks, and sample characters from Seasoned to Legendary make it a great quick reference and help at the table. The examples and sample characters touch multiple genres, from Fantasy and Horror over Modern to SciFi. Design choices are explained to help DIY GMs understand the process even better. After getting this, summoning will never be the same at your tables.
