Could someone post the max bonuses for this guilds modifiable skills due to
being mounted on a chaos steed?

Example we can train mastery of mounted combat to what 50% + some %

Currently im at +16% on this skill myself but i would like to know the caps
for future planning of eq and such.

This could probally be best posted in the web forum but ill take it anyway i
can get it.

As the leader of Tzarakk guild with Wildly Flaming Chimera and "pretty" close
to the Nightmare mount, here is my stats bonuses:
Attack 25%
COmbat riding 25%
DOdge 25%
Mastery of m.combat 25%
Parry 25%
Polearms 6%
Throw weight 25%

So I bet 25% is the top what you can get and polearms might still go to one
percent up or not.
