Question about XP splitting

[Turukano]

If you have an ally aiding you [...] the XP will be split to reflect the amount of damage you each dealt.

I wonder if this is the case for all things that help you. There is more detailed information here:

Experience gain is halved for things killed by your allies (summons, slaves, and charmed monsters).

So my question is if XP splitting also applies to

• divine friends like TSO's angels, Makhleb's demons, Trog's brothers
• the charms/hexes spell spectral weapon
• demonic guardians received by the demonspawn mutation
• anything else (in case I forgot something)

divine friends like TSO's angels, Makhleb's demons, Trog's brothers

XP splitting applies

the charms/hexes spell spectral weapon

XP splitting does not apply (also the case of IB)

demonic guardians received by the demonspawn mutation

XP splitting applies

I have three questions:
1) Is it true that if you dealt some damage yourself you get more exp (75% if half for example)? How does that interact with monster regeneration/healing?
2) Do ball lightnings count as ally kills or you kills?
3) Where in the code is the spectral weapon/battlesphere kills (damage?) isn't ally kills thing handled? Because I tried source diving to feel credible enough to make a post and failed miserably :p

(also the case of IMB)

I believe you wanted to say battlesphere, not IMB.

anything else (in case I forgot something)

pacification, banishment (both from Lugonu and distort weapons)

[lucy_ferre]

Battlesphere (conj) counts as your kill. Servitor (conj/summ) counts as an ally.

1) Is it true that if you dealt some damage yourself you get more exp (75% if half for example)? How does that interact with monster regeneration/healing?
2) Do ball lightnings count as ally kills or you kills?

1. The exp distribution is determined by the % of damage you dealt, iirc.
2. Yours.
