BatoForge strategy notes
Using Ancient Plume
Ancient Plume gives a lone monster permanent +1 Multicast, at the cost of fighting with only that monster for the qualifying battle.
When it fits
It suits a caster worth keeping for the rest of the run, when your Trainer can afford the immediate loss of teammates.
How to use it
Leave exactly one monster on the board before battle start. Pick the recipient before selling or removing teammates, and include the cost of rebuilding afterward.
Example
If a caster has five useful allies, removing them enables the reward. The caster gains +1 Multicast, but must face that battle without any of their damage or support.
What you give up
The Trinket destroys itself after triggering. A weak cast may gain too little from Multicast to justify dismantling a working team.
