We changed Björn to get more combo per attack and regenerate stamina faster to make him more smooth to play and eligible to actually compete on leaderboards against the other characters.
Also we removed the Red Light attack from Immortal Ringmaster as it was deemed not necessary and confusing, amongst other minor changes and a couple fixes.

Changelog:

Björn:
Increased amount of combo points gained per attack to 3
Increased stamina regeneration to 72
Decreased max stamina from 300 to 200 (1 less bar)
Lowered Blessing of Vanir's and it's alternatives cooldowns to compensate for lowered amount of stamina.

Gerhardt:
Increased stamina regen to 40
Overcharge doesn't stack anymore, re-using it while active will reset it's duration.

Kahina:
Increased stamina regen to 48
Increased movement speed a bit.
Adjusted Earth's Might to fit stamina regen changes.

Other stuff:
Combo doesn't get lowered by inactivity anymore, only when taking damage.
Removed Red Light attack from Immortal Ringmaster.
Immortal Ringmaster's walls close a bit faster in general.
Fixed Bermuda Devil music stacking bug.
