Is it possible to get an unbreakable tool in AgS?
I'm not sure if the thaumic and paper modifiers stack or not..
EDIT: Apparently paper tool parts are disabled
I was asking around about this some time ago. The only 'legit' way is I know of:
1: Create a 4-part obsidian tool/weapon [dunno if this is applicable to 3/2 part tools but I doubt it]. This gets you to Reinforced 3.
2: You must get 'Reinforced I' twice as a random modifier. Up to Reinforced 5 now.
3: Master tool/weapon to unlock any remaining modifiers then replace all parts with Thaumium except for the main tool/weapon part [that needs to remain Obsidian]. This should net you an additional 3 modifiers.
4: Fill all remaining and 2 addon modifier slots [for some reason Nether Star modifier addon doesn't work for me?] with Obsidian plates [5]. Tool/weapon should now be at Reinforced 10 = Unbreakable.
I was doing this with a Scythe in an AA [weapons/tools will level quickly in an AA]. Problem I was having is I kept getting Blaze modifier along with Reinforced I, making the tool unusable for mob Tower [blaze sets Endermen on fire - causing them to teleport]. After 3 barrels of Obsidian, I decided to cheat a bit and make my own.
To cheat one in, you have to change some configs to unlock everything you need and disable tool leveling/modifier removing. Cheaty version requires 2/3 paper parts and main obsidian part, plus 1/2 of the additional modifiers. You can also use Thaumium but I found paper was giving more modifier slots? Assemble as usual and when tool is unbreakable, you can change the configs back.
--Make sure to use it once before changing configs back [verifies it's unbreakable and precaution against modifier removal on newly created tools/weaps].
There's also the Thaum repair enchant. Someone prior told me Repair II will keep a tool/weap unbreakable [untested by me].
