I already have 17 skeletons and 17 mages. The physical damage is strong because I use beast and a merc with pride...is there anything other than revives to put my remaining points into? Would it be useful to have a fast clay golem?

amp and CE

CE for sure, best players/1 clear in the game.

Other options:
Golem mastery so you can make an awsome Iron golem for extra aura.

Fire golem/master for a cool tank that keeps aggro

Bone armor/synergies for defense (Not like you need it but well Dolls exist)

anything that sounds fun or wacky is great aswell

of course i use amp

Amp for radius
CE for radius
Golem mastery for durability
will be your best options

Also use might aura merc, and enchant your skeles that’ll boost their dmg, either chant sorc or demon limb with a 5/5 fire jewel

yeah here's my enhancements: amp damage, beast, might merc using pride cryptic axe. i have the usual gear (enigma, beast, shako, 35fr spirit monarch, toch/anni, 9x 30+life gcs) also i decided to use marrowwalks for its mastery bonus.
i have no trouble killing monsters and staying alive. i decided to put the rest of my points into golem mastery and clay golem...I'm not sure if its serving as a meat shield or not lol
i don't have demon limb yet but that's easy to get.

Use Bramble armor lvl 21 thorns that’ll help the skeles to!

But summons can't be controlled without teleporting...

Use it as mercenary’s armor
