Here is original immune reload build that helps you to immune to damage from buckler.
Guide to Immune Reload Build
This is a build that will make you immune to damage and deal 25 damage every turn.
So you must have:
- Bad cheese
- Only one ball.
So you discard your ball every turn dealing 25 damage from bad cheese and making you immune to damage from buckler.
Note: Its slow but it works for every fight except for the last Boss where they will out heal your bad cheese, so make sure you have some way of killing them.
