The live boss script's rain of fire takes every target of the first ROF target group and ROFImpactCnt (2) different
random targets of each other group. The server took one per group, so the rain was sparser than live. The impacts are
now picked like the live script (without repeats inside a group).
Check in game: AG Spider Queen stage 3; the rain of fire lands on the centre ring and on two spots in each outer ring.
