This is an AWESOME idea! Why developers did't consider this so far?
The potion like idea and the enchanting like ideas make the perfect tecnology conunterparts of old stile spells and alchemy of vanilla version. This can also apply only on IC2 objets, so they can't staks with enchanting...
From SpwnX ideas:
-For the nano injection there are no particular develope issue i think, the effects are the same of the potion, change only the way they are created, maybe in a dedicated energy-eater machine, something like "nano tech lab".
BUT i think that all in one body is too power... if they duration is upon death, have all the 5 boosts always on with a quantum suit charged make u almost immortal... i think that 1 at time is more balanced, if u take a new one, u overwrite the old one... it's for LIFE man! Do u imagine regeneration always active??? they must be in a MINIUM of 10 mobs for kill u, this MUST require 4 advanced machines and 4 iridium plate into the crafting process to make regeration nanobots!
With this u can also produce "un-programmed nanobots", stored into empty cells for the nanocircuits recipies, or also combined for other propouse like even better fertilizer!
-For the nanocircuits... i see it like the naturally IC2 enchanting mode: change the way u reach the goal, instead of experience, expansive material and lots of energy, but free us from the casuality factors!
We choose what to implements!
Following the SpwnX list i make the modification that i think is necessary...
Tools:
Energy Efficiency circuit: Reduces Energy Usage by 10%/20%/30%/40%/50% (good thing)
Mining Efficiency circuit: Increase block break Speed by 3%/6%/9%/12%/15% (idem)
Mining Precision circuit: Give player a chance to get double, triple, quadruple drops from non-player placed blocks by:
I: 30% * 2 (30% more)
II: 15% * 2, 15% * 3 (60% more)
III: 25% * 2, 25% * 3 (75% more)
IV: 15% * 2, 15% * 3, 10% * 4 (100% more)
V: 20% * 2, 20% * 3, 20% * 4 (120% more) (following the enchant table, this seems to me more correct, remember it's PERAMANENT!)
Nano Processing circuit: Give player a 20%/40%/60%/80%/100% chance getting the original block. (why take damage? the tecnology allow us to do the things in the safest way HAYO!)
Integrated charging circuit: Increase the recharging speed from Batpack/LapPack for +1/+3/+5/+7/+9 (this means that at level 5, 1 use charge up 10 uses!)
Battery circuit: Increases energy storage of item by 10/20/30/40/50 EU. (Flat bonus are easier to quantificate)
Weapon:
Fire saber circuit: Sets enemy on fire for 3/6/9/12/15 seconds (good)
Light power circuit: Increase Nano saber/Mining laser point of damage by 1/2/3/4/5 (this 2 are already deadly like they are...)
Explosion boost circuit: Increase explosion of Mining Laser explosion mode by 10%/20%/30%/40%/50% (boom boom boom)
Blast circuit: Knock back the target by crescent distance (New one!)
Machines: i don't think this is applicable.
