An idea for artwork for a room card suggested by GriffinPatterson. I think that giant octopus fits the general concept of this room: It has relatively high damage value for a thief room, and creature's tentacles somewhat correspond with "item stealing" ability.
An alternate colour variant for Muddy Pond room card.
An idea for artwork for another room card suggested by GriffinPatterson. I think that Tomb of Cursed King suits well not only cleric treasure room but also items collecting concept.
An idea for artwork for room card originally created by GriffinPatterson on BGG forum, with more balanced ability suggested by Koey. Originally it was named Magic Missile. I think that dragon statue serves well as spawner for those magic missiles. The dragon statue design is based on statues from Legend of Grimrock RPG.
Custom bosses cards (still somewhat work in progress) created as a tribute to Spiral Knights and based on bosses from said MMO. Level Up abilities and XP still need to be tested and balanced.
