Lately I was thinking about, how the Kensai would fare, if they had the same, effective
AC progression of the Monk, instead of having the untyped -2 bonus to AC at Level 1.
It would make sense for a Kensai to develop the same skill of avoiding attacks, since they don't wear armor, gauntlets/wrists and helmets. Also unlike the monk they do not gain the many passive protections, like spell resistance.
Here a progession table with the XP caps for fighters in this order: BG1, SoD, BG2 and ToB<<Level>> | 01 02 04 06 | 08 10 | 12 14 16 18 20 | 24 27 30 35 40
Effective AC | 09 08 07 06 | 05 04 | 03 02 01 00 -1 | -2 -3 -4 -5 -6
Usually if a vanilla Kensai/Mage opts to wear a Robe of the Archmagi, he gets the effective AC of 5 with the -2 bonus having a total AC of 3.
If the altered Kensai was to dualclass to a mage at Level 13 and regains the Kensai abilities at Mage Level 14, the effective AC of 3 would overwrite the AC given by the robes.
Likewise if a altered Level 21 Kensai dualclass to a Thief and gains the HLA Use Any Item, there won't be much of a change if the kensai/thief decides to carry a full plate mail.
However, what the effective AC allows is to wear armors and robes with better bonuses in other areas.
The only real con is, that a altered Kensai in the early game with the Shield Amulet will have a AC of 4, instead of 2 in the vanilla game.
So my question to you fellow gamers is this:
Would you consider playing a Kensai with a effective AC progression?
