Alignment Change

From HGWiki

Pre-immortality you will need to keep to specific alignment axis to be able to carry on levelling up your character, whist this is not required post immortality you may find you are not able to cast spells or benefit from certain abilities if you change alignment as noted below -

Paladin - You will need a Good alignment component to be able to cast spells and keep the Divine Grace bonus to saves, you do not need to be Lawful Good though.
Blackguard - You will need an Evil alignment component to be able to cast spells and keep the Dark Blessing bonus to saves.

Good / Evil axis

Pre-Immortal only: Talk to the priest in town near the Rowan Tree, give donation for good, stab in the back for evil.
Good: Bury an anointed corpse in the small cemetery in the town. A shovel is needed too (from behind farmer Bobs house)
Good: Free tortured prisoners from PoM map 2.
Evil: Sacrifice an anointed corpse at MoaD altar.
Evil: Kill prisoners from PoM map 2.
Evil: Kill some Pharlans in Rona or good creatures in Elysium or Oinos.
Evil: Kill some peaceful animals (e. g. north of town)
