Seems like a simple word proposal issue would be good. My suggestions for words:
Actions:
flauga
- fly, probably gives the effect of temporary creative mode flight or simply just floating upwards
flautja
- float, stops vertical movement for a moment
fram
- forward, moves something forward
kveykva
- lightning, probably fires lighting either from the sky or from the character (like Star Wars force lightning, I think I have a way I can handle the effect)
letta
- stop, not sure what to stop, possibly all active effects, or continuously running magic effects
slytha
- sleep, disables and blinds entities, possible forcing players asleep for a moment (if possible)
vakna
- awaken, cancels slytha, and forces sleeping players to wake
thaefathan
- thicken, may be an effect, an action, or something in between, requires better suggestion
andask
, deyja
- die, another death spell, maybe more severe, but also more costly
frethya
- hide, tries to run invisibility on entities
galdr
- spell/enchantment, possibly for wards?
haina
- harm, damages entities
hlaupa
- run, gives speed effect
ignasia
- shine, forces applied entities to glow
istalri
- fire, same as brisingr
ladrin
- open, forces selected blocks to open, damages entities?
Selectors
eka
- I, same as edtha
hurdh
- door, selects closest door
adurna
- water, selects nearby water blocks
I may add more to this list if find anymore good words to add
