I just remembered something: Hell's Arena has 3 waves, and I think that one nuke only clears one wave. So, there might be a need to have three different messages for nuking Hell's Arena depending on which wave it was, or rather, how many nukes were set off in Hell's Arena.
So, two things. Firstly, someone needs to test it on AoRA to see if the nuke that goes off then only clears wave 1 or everything. Secondly, realise that it is almost impossible to get three nuke-like things going on Hell's Arena, which is dlev 2/3.
O.O
