HotM in a bottle
I use more harpoons, titanium shields and panacea against triple seasonal bosses/ class quests than titans.
Never have enough of the correct titan parts.
If I Recall correctly, most of my accounts have much fewer 5* HotM than your main account.
Harpoons
Though harpoons are awesome for titans.
Never have enough iron.
Alchemy lab
I might actually build Alchemy lab if it requires titan parts instead of gems.
