What gear to use on Titans

The Titans are exceptionally strong bosses that have 12 levels, each doing more damage and having more health than the last. There are 6 titans, one for each element, fire, poison, metal et cetera.

Titan element ground/flying and melee/ranged
Magnus Machina Metal Flying and Ranged
Queen Katla Fire Flying and Ranged
Assault Platform Krab Ice Ground and Ranged
Arcane Monarch Otto Magic Flying and Ranged
Slime Tyrant Blobbius Poison Ground and Ranged
The Storm Harbinger Lightning Ground and Ranged

Please note that even though a Titan is a certain element, you can use other element heroes against it, if that’s how that day is set up (for example Magnus Machina is metal, but there are days where you have to use other elements against it, such as fire/ice). And also note that as of now The Storm Harbinger isn’t added yet, so not much is known about it
