Huge differences in Power consumption between all three realms and all three realms get their final version around the same level:

The Sorcerer's spell cost 10 or 8 more power than the Champion and we do either the same amount of debuff or 1 point lower.

The Eldrich's spell compared to the Sorcerer costs 16 or 14 less power to cast than the Sorcerer and does either the same debuff or 1 point more

The Spiritmaster is the same except for power consumption which is 10 or 8 points less than the Sorc.

=========================================
SINGLE STRENGTH DEBUFF

Sorcerer / Cabalist
Level 46
Str debuff of 46
Power cost 30

Eldrich
Level 50
Str debuff 50
Power cost 26

Spiritmaster
Level 45
STR Debuff 46
Power cost 23

Once again the Sorc and Cabalist get screwed.

Sorc/Cab power consumption is 4 points higher than the Eldrich and 7 points higher than the Spiritmaster.

The Sorc/Cab is 4 points lower in the actual debuff from the Eldrich.

the Sorc/Cab are on par with debuff with the Spiritmaster.

============================================
SINGLE DEX DEBUFF

Sorcerer and Cabalist
Level 46

Power cost 22

Eldrich
Level 48
Dex debuff - 48
Power Cost 31

Spiritmaster
Level 36
Dex Debuff - 38
Power cost 23

This is an odd one....

The Sorcerer/Cabalist gets his last spell at level 46..costs 9 points lower than the Eldrich and 1 point lower than the Spiritmaster

The Eldrich does 2 points more in dex debuff

The Spiritmaster does 8 points less debuff than the Sorc/Cab and 10 points lower than the Eldrich
