A Risk of rain 2 mod that carries over (some) of your Bandit stack tokens from the desperado ability.
What about PersistentDesperado?
To be honest, I didn't even know about it until I preety much finished and since I was doing this to also do some C#, I decided I'll do it anyways. The mods do differ in the balancing aspect, so its not just a duplicate.
Balance is addressed in form of a multiplier, which is applied at the end of each stage (stacking tokens * multiplier).
The multiplier works as one would expect it to (0 - remove all tokens, 1 - keep all tokens, between 0 and 1 -
remove only some of the tokens, above 1 - go nuts :) ).
The config should contain only one number which represents the multiplier. Suggested value: somewhere between 0.5 and 0.75.
