Combat RNG
Combat RNG describes the random XP gains received from the “Random Combats” modifier. Each enemy in our path can be worth differing XP, and therefore sometimes less. This is a feature exclusively of hallway fights, as neither boss, nor event combats have random enemies.
Due to XP clamping, combat RNG is seldom a relevant factor in any given run, but can at times pop up. If you feel like you are behind on score at any point during a run, but youve followed the node guide perfectly, this is likely the next factor to think about. As discussed in the clamping page, most of the XP differences in the early acts are irrelevant, as long as the XP gains are generally optimized. But as we get into act 3 and especially act 4, this factor becomes relevant and can have minor score differences.
All of this, plus the 40% for great combat performance, plus jade scarab(not affected by combat performance) minus clamping is…
((58 + 58 +53 +61)*1.4) + 200)/10)/4) = 13.05
Rounded down to 13 XP per character.
Loading a save before the fight, then using Seed_Changer, we shuffle the combat to a new set of enemies.
((58 + 58 + 70 +60)*1.4)+ 200/10)/4) = 13.61
Rounded up to 14 XP per character.
We can see that by rerolling the enemies, we have managed to get a small XP gain. A 1-2 XP difference per combat is extremely small, but if we did this for every combat, it can add up overtime. The difference between a run that is optimised in this way and one that isn’t is likely in the score differential of about 50-100.
As of December of 2025, this page is OUTDATED. Due to the new mod EXP Normaliser, none of this information is relevant. The page remains as a lesson in why the mod exists.
