Smouldering Tome is a legendary major card out of the New mechanic pool. Tome Pulse leaves its circle smouldering for 4 s at 5% damage per 0.5 s; the pulse is 80%.

You can take it once · it only turns up when your Special ability can actually use it · it can be offered for 0 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Twin Tome and Great Tome. Take one and the rest are gone for the run.
