Monks that are fully progressed are excellent dps. And building one correctly can yield an almost magically immune tank. Dont be fooled by the robe!
Let me list some things I remember they get by not multiclassing according to 3.5 rules
Level 20 Monk:
DPS
2d10 unarmed attacks(medium build) 2d8 (small build)
Flurry of blows maxed to like +5 additional attacks I think with no penalty (no need for twf, itwf, gtwf, stwf)
*May use kamas, quarterstaffs, shuriken. so stock up on vorpal, paralyzing, and maybe even a nice +X maladroit Qstaff of bone breaking.
Quivering Palm Fort save on successful hit or death (DC 10 + 1/2 the
monk's level + the monk's wis modifier)
AC:
Wisdom Bonus = AC ie. a 20 wisdom wearing no armor or shield AND is unarmed yields +5ac
Innate AC bonus: +4ac at lvl 20 just cus DnD loves monks
*So to make it easy to figure out...
AC Bonuses:*easily attainable for experienced player
+4 20th lvl monk
+6 @22wis
+10 @30dex
---------
+20 AC
+10 naked starting
+1 dodge
+2 chaos guards
+6 dragon robe
+2 ring of stability
+5 pro item
-------
46 AC unbuffed and comparable with tank classes
*not getting into pots, CE, chatterings etc. BUT I bet there will be some monk gear, enhancements etc.. that will enhance AC.
Dex or Str you ask?
answer: Depends on personal preference. If you want a human then spend the extra feat on power attack WITH weapon finesse, and keep the high dex for ac, reflex and +to-hit. Btw, kamas are finessable
Other nice things:
High Saves: All
Still Mind: +2 saves vs spells and enchanments. *stack with dwarven? hrmm
Immunity to disease and poisons
Perfect Self:DR 10/magic
Spell Resistancemonk lvl +10 starting @lvl13. So
SR 30 @lvl20!
Evasion and Improved Evasion: nuff said...
Adamantite/Lawful Fists: @16
Wholeness of Body: Heal yourself for 2x your monk lvl each day. Good spot for an enhancement dont ya think?
+50% run speed: @18
Empty Body: become etheral twice a day, displacement spell basically
Stunning blow and Cleave *sometimes left out as automatic feats
Other things to think about:
Dont forget monks must be Lawful
1D8 hit dice CON/Toughness more important
Monks Base Attack Bonus: Medium, so they are totally dependent STR or DEX for unarmed attacks. *Not sure about +Attack bonus gloves so it kinda forces us to wait or go totally in STR or DEX direction.
Dragonmark Feats for Healing?
Halfling Monk: pros: AC bonus +2Dex @start and enhancements, more saves avail, and who doesn't love them!?!
cons: 2d8 fists, -2str @ start
Dwarven Monk: pros: +2Con @ start and racial bonus, dwarven toughness, hardiness verse spells
cons: none
Warforged Monk: Too early to even begin thinking about. Could start a whole other page on possiblities.
