That the illusion table is 'a work in progress' is noted. Still, it certainly seems to solve the Phantasmal Force vs Spectral Force problem. At first glance, I like your solution, and the 'Behold' spell is an elegant bit of deviltry. One question regarding your backstab explanation: Would the thief hiding in the alcove have required a Hide in Shadows roll? I mean, even a fighter in chain mail ought to be able to hide in an alcove. My point dovetails with yours about someone with a DEX of 17 automatically being able to catch a tossed potion. A thief, skilled as he/she is at hiding even at low levels, should automatically be able to hide somewhere that offers full cover, such as in the previously mentioned alcove or behind a bookcase. The trick to Hiding in Shadows, I suppose, lies in being able to mask one's presence behind 1/2 cover, 1/4 cover, or even in a corner which lies in shadow. Your commentary about allowing a backstab during combat under virtually all conditions is logical. Some DMs will disallow a thief's backstab because 'the monster knows you're there', whereas other classes would be given a +2 bonus to hit if their opponent merely turned their back on them during combat. This is unfair. Thank you again for answering my query so thoroughly. I look forward to more additions to your blog. If you have any thoughts or house rules regarding 'fighting retreat', I'd be keen to read them.
