I’m trying a new build
Wiz->Pyro->Link->Thauma->Thauma->Thauma->Run(now) ->Enchanter
Here’s the video:
Sacrament + Cafrison + Enchante Fire + Rune of Giants
This build may be stronger in the coming new patch because of these changes:
-Swell Left Arm will provide additional 120% damage when attacking Shrinked monsters
-Will be able to use all the skills in Giant mode
-Giant mode will increase HP/Pdef/Mdef by 20% (Actually a nerf but it’s still good)
Anyway, this build is full of fun 
I was also testing similar build, together with Power Staff.
Unfortunately it doesn’t work with the Giant Stomp, and my bad ping doesn’t let me jump attack very well 
I have a Wiz3 > Link1 > Sorc2 > Rune Caster
Is fun to play, being giant with the summon, attacking together, casting runes while the summon es tanking for me 
sorry for bad english
… All skills can be cast.
Time to become the ultimate Ice lord purely to exploit the 20 movement speed boost.
(Who cares about rune of ice…)
