Defending the Vault were 2 magic servants. I thought to myself that the water was therefore the main barrier as this did not look particularly challenging. Sadly, the Vault threw 3 cosmic sprays at me, which hit every time despite the elemental's 14 resistance. On top of that the first magic servant hit the elemental twice and the second once so that did it in. The strange part is coming up...
I reloaded the game and tried it again. Again the cosmic spray hit, funnily enough doing precisely the same damage as last time. The first volley of shots from the magic servants missed, just as they had the first time. On a whim I moved the elemental to the same spot I had during the first round of the last battle. Again a Cosmic Spray and again the same damage. Again the magic servants and again the same numbers of hits... in the same order as in the last battle.
Strange, no? I repeated the experiment over 10 times and never got the least bit of variation unless I did something differently... and if I did something differently then did it again, guess what... precisely the same results.
Now it just does not seem feasible to script battles, there are simply too many variables (or so one would think), so my question is... what is going on?
