the runic transference talent is super handy to uncurse and enchant an armor in one turn without wasting a scroll of remove curse, stone of enchantment, arcana stylus or scroll of enchantment, just detach the broken seal from an enchanted armor and affix it to the cursed arnor and you will get to choose between the curse and enchantment, which is super useful i think
I think the most useful part is the upgrade transference on early - mid game. Use the first upgrade scroll you find on your leather armor (just one) so you can use armors with 1 less strength, and have early armors you're not really gonna invest in an extra upgrade, which is really useful.
The second best use is, when you have an armor with several upgrades an a glyph you want to keep, detach the seal with the glyph, upgrade the armor and then reattach the seal, so you can upgrade your armor and keep the seal.
