Maybe but hwoever it works on Thay, monk-rogue is arguably better than monk-assassin for diversity and dmg, only advantage would be the death attack and some innate spells.. but those are easily acquired through scrolls and wands (rogue UMD) and death attack only works well on low fort creatures and require high int to be effective. May as well just stun fist and pommel and get alot more skill points from taking rogue. Thay uses a non-auto 20 for UMD checks though so that may be where having innate spells would be handy
