Description
Description
The mod adds (soon to be) a set of cards that will blend into the vanilla character decks.
Installation instructions
create a new folder in the Slay the Spire 2 directory (accessed by right clicking the game in steam and hitting browse local files) name the new folder 'mods' then drop the mod folder from this page inside. When loading the game with mods it creates a separate set of profiles specifically for modding, so unmodded save data is fine once mods are removed.
Main features
cards added:
energy bomb (colorless 4 cost, 12 * 4 damage, +2 damage & +retain on upgrade)
Shout outs
Thanks to the Slay the Spire 2 discord modding channel for some help learning the modding process.
