Ran my first 4E session in FG today, ran into some questions...
Everything went more or less smoothly after the players got the basics down, I'd imported their characters earlier this week and set up the encounter ahead of time, however I ran into a few snags where I couldn't find an immediately obvious solution.
1. Tweaking rolls. I couldn't find a way to override a roll after FG had decided the outcome. For example, player makes an attack, hits 2/3 of the targets, forgot he had combat advantage that would've made him hit the third as well. I couldn't find any combination of clicks to tell the program to turn the miss into a hit before he rolled damage. Also, player attacked an insubstantial target, it takes 1/2 damage from non-force attacks, FG makes the attack do 1/2 damage. Except it was a force attack, so I clicked on the damage result to try to tell it to not halve the damage and could change the damage result in the chat window, but not make the change take effect on the target in the combat tracker, I had to go and manually change its wound total.
2. Applying different modifiers to different targets for an attack. Swordmage wanted to Sword Burst, which would hit two targets. One of the two was granting combat advantage, and should have a +2 that the other doesn't. I couldn't find a way to quickly stick a bonus to his attack roll on just one of multiple targets; if I used the modifier stack down in the lower left corner or opened the party modifier window and clicked on Combat Advantage, his attack would use that for both targets instead of just the one target that it should have affected. I tried dragging the number on the modifier stack to the one monster it should be applied to, but no luck.
