Opinion.. End Game use of Isle of Dread Crafting

[Xoetep]

Currently I'm using a regular Isle of Dread staff..

Acid warlock.. mid to high 800's caster power..

Acid Crit multiplier 135 and force 130.

I have 104 to 106 in enchantment, necromancy and evocation dc's. the rest around 98 to 100.. not that the other schools matter for my build.

The staff gives me double implement bonus from Dragon epic tree and the staff gives me a +2 to spell caster dc's.

Are Dc's dropping by 2 a big issue on high reaper? When considered that I could switch to a stick and orb or 2 sticks getting an extra set of dots from claw and horn?

Are dots better at end content or the +2 to dc's from the staff?

Currently I'm getting the acid dot from a ring and "untyped damage" from the staff.

I could add another acid dot.. and even the curse dot..

P.S. I do have the freeze effect on the staff which is easy to get again.

Redundant. You just build stacks slightly faster, not double DoT effect...

OK.. but is a 2 point drop in DC's worth adding let's say a fire dot or a cold dot as well as the curse effect with an untyped damage?

Yes. Thanks to the D20 system dropping DCs by 2 means an extra 10% chance your spells will be saved in content where you have not reached no fail. For nukers the trade off is usually worth it. For DC casters its not.

I could add another acid dot.

The acid dot from Bound Elemental Ring of Acid and Meltfang are the same effect so dont stack.
