Yesterday's random card was Day's Undoing. Hey, that seems a little familiar. So I rerolled and got Stonespeaker Crystal which is already a dnd thing! Finally I got Cytoshape.
Cytoshape
Range: As far as you could throw a rock. Duration: [dice] turns. Targets: Two creatures within range with HD less than or equal to [2*dice]. (Or max HP less than [2*sum], if your monsters don't have HD.)
One target becomes a copy of the other target for the duration of the spell.
Spell-specific mishaps
- Instead, the two targets swap forms for the duration of the spell.
- All creatures within range become copies of either target at random for the duration of the spell.
Additional notes
The nonlegendary clause on the original card is just to keep it from being a kill spell, there's no need to port it to GLOG.
