Someone Help Me With A Build :3

So... I got a Grandmother, and its kinda underwhelming, especially the HP regen, but that is without a proper build to go with it.

I'm thinking about doing a Spell Damage build, so currently, I'm thinking:
Spectre
Mummy's Rag
???
Slime Boots

Suppression
Suppression
Ra
Golumlus Core

Any suggestions? I was thinking about Vaward, but it seems like there would be better stuff.
Also, Suppressions are kinda weak b/c of the mana steal, and because my melee is slow, it's like a 33% chance that I lose half of all my mana. Any better rings?

Also, bonus pic of me afk'ing with grandma equipped.

jester set for the spell dam?

 

I was really confused until I realized that you meant "grandmother" as the item

 

Naw, thats raw spell damage, which is only good in arrow storm. I don't wanna lose the golumlus core or Ra because if I lose em, then I take wayy to much negative health regen damage.

 

what has negative health regen on this build?

 

The grandmother lol. As in, a SHITTON.
Mine has -340 raw hp regen and -27 percent hp regen.

 

I have some Dead Sands that have like -38% health regen.I feel your pain.

 

If you don't mind losing a bit of mana regen, there is

Spoiler: this

as another option for rings.

 

Oi shit. I completely forgot about that... Too bad its expensive as fuck. I may buy one once I save up enough cash.

 

Zz get electrocharged greaves tier 2 to make ur grandmother be super fast if u have tier 2 mummy rag

 

See, I was thinking about that, but it raises several problems. First and foremost is that I’d have around 6k HP. Secondly, Thunder and Earth doesn’t stack well at all. Thirdly, Electrocharge gives a pretty significant melee damage decrease, and my current pair decreases earth dmg by 10%, which is actually pretty damned good. Lastly, and probably most importantly, Electrocharge costs 65 dex. My current skill point loadout will have to be 100 strg for Grandma, 25 def for Golemlus Core, 35 agil for Spectre. That’s already 160 skill points. I’m not sure how I’ll manage to fit that 65 dex. I’d replace Spectre with something else if I’m able to.

 

Blue Mask solves everything c:

 

But then I'd have even lower HP ;-;

Anyways, I'm kinda hesitant to put on Spectre as well, b/c of 35 agil and 5% negative earth dmg and a bunch of negative melee dmg

 

say, if you're already using spectre, maybe Breezehands could work? idk the agility req for it though.

 

55 agil, 55 dex, still kinda high ;-;
