Will the horizon walker's favored terrain, terrain mastery and terrain dominance work the deepwalker's deep knowledge ability? I realize deep knowledge replaces favored terrain, but at the same time is very much the same thing just more specialized. Thoughts? And if so would at deepwalker 6/horizon walker 3 with boots of freindly terrain(underground) would he/she be setting at +10 hit/damage/initiative/pertnant skills to anything native to underground? Also in the beastiary's "Monster's by Terrain" are mooks listed to be found in "Any Terrain" included in this +10 you die scheme?
Thanks
I think that the Favored terrain and the Deep Knowledge would stack for the original bonuses as they are both untyped bonuses, but your bonuses for Deep Knowledge would not stack with your Terrain Dominance for that specifically calls on your Favored Terrain bonus to be converted.
I believe you would have only a +8 to Hit and Damage creatures native to the underground and a +10 to Init and Perception.
