Bumba Magic Defense And Geomancy Resistance

Bumba has 122 Magic Defense.
Geomancy is reduced to 15% effectiveness => 85% resistance to geomancy.

Notes;
-There is a 25% reduction to all damage in v25.
-Based on notes translated from Xolla's video for V25 Bumba clear "It seems that after regenerating scales, the boss gains DT, and when you exceed over approx. 10,000 damage dealt, its DT goes up by about 0.75." My testing did exceed 10k damage in proc mode during 5 runs and Bumba did gain MDT. The 10k damage is cumulative, it does not need to be 10k in a single action.

Appreciate you doing this kind of testing for endgame mobs, Its nice knowing their stats even if you don't need to know. Always enjoyed the amount of testing the community did to figure out these kinds of things back when more people played.

wish we knew more about mob defense for example for current endgame bosses, given your Arebati testing seems like most current endgame defensive values probably far exceed the apex values most sims/spreadsheets are still using.

Keep it up friend.
