Guides

I'm bookmarking this, @Starrybrow!

Here's another build I don't see on your list, and one I'm thinking of trying out: @celelorien's GW fodder duo build

@Starrybrow Yay! I remember coming across a way-strong build recently too so took a shot of digging it up for you. Were you thinking of this "Shattered Cannon" build? (though it looks like it perhaps needs to be updated to a 136 build for GW?)

hayum: 133 Build (Shattered Cannon Build)

@Starrybrow,

ETA: I guess I spent too long editing my post--someone posted the Shattered Cannon while I was working on it. As far as I know there haven't been any updates to the Golem Workshop that prevent this build from scratch-eliminating all the enemies; I just took a team of three STR 133 dragons in for a quick check and I haven't noticed any changes, although I haven't encountered all the enemies yet.

Hayum's STR 133 build or "Shattered Cannon" for the Golem Workshop/Kelp Beds, plus their "Quick Healer". (While Hayum doesn't mention this, the Shattered Cannon build is also pretty useful for the Crystal Pools and Harpy's Roost, since it can one-shot eliminate all but two of the non-boss enemies in both those venues.)

Junipa's Golem Workshop grinding team (as I recall this was the first Golem Workshop guide!):

Maki's Battle Stones guide has a section at the end with a few different builds--most of them are already in your list, but not all of them. There's another Golem Workshop leveling duo, plus specialized builds for farming or leveling in the Crystal Pools (never tried those, no idea how they work) and a couple different team configurations for farming in the Golem Workshop.

Halamshiral's mage guide:

The build from there that gets used the most is Sunreon's healbot, which is really useful in the Golem Workshop.

Not exactly build guides, but still useful and/or fun:

This is a tool for elemental composition of teams! With a lot of team builds the elements don't matter, but I like this thing anyway.

And for anyone who wants to experiment with their own builds, Sylvandyr's stat preview and damage preview tools are extremely useful.

@Starrybrow

This is a really helpful guide! I've been looking for something that puts all of this in one place, especially the stage specific builds.

(Also, the spelling is Golem, not Golum, just so you know :) )

@Starrybrow Thanks for putting this together, it's really useful!

@Sheliak I hadn't seen some of these before, this is great :D

I can confirm that the 133 STR Golem stated dragon needs to be 136 in order to beat all the enemies it could at 133 which are not specific to GW, this dragon works for Kelp enemies like mammertees and depins.
