[Magiclysm] New spell for shapeshifter

[GuardianDll]

Summary

Mods "adding new attunement spell for shapeshifter+fix the alkahest lack of spell_class"

Purpose of change

#45011

Describe the solution

Buff spell with quite small cost and not so big effect, but allows to stack it to 25, giving +10 to all stat and pretty good stamina regeneration, but also require to train it for decreasing the price

Describe alternatives you've considered

something another
change the effects

Testing

Works fine

Additional context

Duration feels pretty small, but each cast increase the lenght of the effect, so with duration 5 minutes and 25 effect level it lasts [ 5 * 25 = 125 ] nearly 2 hours
also small fix, cause alkahest has lack of spell_class
maybe it require to change the spell name/description? 🤔
