Celtic Heroes

Hi people , i have no sigils ! (Lvl 145 , second best mage of epona without sigil , first s 147)
Can you guys post an answer for builds without e shield and with e boost
1-with firestorm
2-with incinerate
3-without ice shard

(3different build , its not requirments for only 1 bild)
Atm i use a :
Max ice shard / fireball / eboost / cloack build
And a 25 firelure
And a 15 icelure
It work pretty well

Sorry if this is off tolic but seeming as your a experienced mage whats the best gear like it arcane irb is worth it..

The book give me 100 focus which give me more than 10energy/tick on e boost + add dmg on others skills
So the book is better , exept for tanking ofc
