Hello there

Glad to have finally someone to talk with.
I disagree on rating Peace of Mind so low. Besides providing a good bonus for your primary stats (5 on lvl 20) and increase your Crit by a lot (11 Wits on lvl 20), which is a must for an archer, clears Charm and Terrified, the two more annoying status when the enemies inflict on you.
You are quite right about the stat bonus for 1PA. I changed my answer to 3/5. As for clearing the charm and terrified states, in 152h, I was never charmed once and got terrified only once so I don't give a lot of credits to it even though it is still nice to have.
Also, Superconductor and Binding Radiance is good but their range are limited
Well as Supernova, they are quite limited but their stat scalling make them really good damage sources. And I think that "blind" is a statut that is relaly nice until the end of the game.
Please reply to the "poll" thread with your own anwsers on all the skills. My post is not the average data of everyone but my own feeling

Sorry if it was not clear enough. I hope you find the time to reply to it because I know it takes a good amount of time

Restoration is the first healing spell you get, cost only 1AP to cast, heals a good amount and if you have Living Armor on the target, restore a little of MA. So, IMO is underrated.
Well 3/5 is for me the perfection. It means it is not too powerful or too weak. It means you will use the spell when you need it. I rated other spells a bit higher like Healing ritual because that spell can, in addition to heal your party, bounce on undead enemies dealing massive damages.
Arrow storm is awesome: the damage is through the roof, hit a lot of enemies and doesn't hit your party (I think at least).
I did not test it yet. Please add your rating when you will put your own answers in
this thread ^^
Laser Ray is one of my favorite spells of the game, it have one of highest (if not the highest) damage of non source spells, can hit multiple enemies without having to decrease the damage you done and is available very early (Driftwood).
This skill is definitly one of the main damage sources of a mage. I totally agree.
To be fair, the usability and usefulness of a lot of the spells depends on your play style. Maybe, is easier to agree on the really underpowered ones, like Dimensional Bolt
That is in fact what I wrote too. But it still will help to see if a spell is regarded as average or powerful by the community. But the notation will never be perfect alas.
