Items for Synthesist

[Coinshot Colton]

Got a biped synthesist that I'm trying to outfit. This is a new character, so any item I swap is still at full price right now, since it's still in the character creation process.

Half-Elf Synthesist (Biped) level 7:

Str 24, Dex 15, Con 13, Int 14, Wis 14, Cha 21
Fort +7, Ref +7, Will +10

AC: 30
Attack +14/+14/+14/+14, 1d6+10

Currently have:
+2 Str belt (4k)
+2 Cha headband (4k)
+1 Amulet of Mighty Fists (4k)
+1 Cloak of Resist (1k)
Eidolon Anchoring Harness (6k)
Ring of Sustenance (2.5k)
Wand of Lesser Rejuvenate Eidolon x 2 (1.5k)
Total: 23,000 out of 23,500

So I'm wondering, should I trade in the Anchoring Harness (6k) and upgrade the Cloak to a +2 (+3k), and buy a Ring of Protection (2k)? I'm immune to sleep, but I'm pretty wary of banishment or dismissal, as well as just getting pounded in general, as the DM pits us against some really tough opponents. Is the Harness even worth it, or should I just rely on using Summon Eidolon if he gets dismissed? Another thing is that I'm a bit worried about being critted. With the Harness, it'd give me time to heal the eidolon before he goes away.

Any "must-have" items that you guys can think of for the near future would be appreciated as well. Synthesist doesn't seem to have much items to really shop for, which is great I guess.

Hmm... I have to say that your item choices are absolutely perfect. You've got every core item you need, should definitely keep all of them. No need to re-purchase.

As you get more gold, I'd upgrade your items, your cloak and your belt chiefly. Little else seems crucial.

Well done.

So you think it's better to keep the Harness and get the cloak upgrade and ring later?

[GM Arkwright]

I do. Particularly if you're anticipating a dismissal/etc-happy DM. Maybe upgrade your cloak further instead of getting a ring, up to you.

Anyone else got any thoughts on Synthesist items?
