Looks like my character despite her "odd" backstory is getting very good.
Managed to complete the Act 1 :
then in the middle of Act 2 finally the blacksmith manged to forge something awesome from the bunch of metal scrap i was giving him (1 awesome yes ... but for hundred of crap not corresponding to my weapon skill of chocie i must say)
And finally completed Act 2 after long bunch of battles against hundred of robots with insane amount of health
And not yet started on the Act 3 but the repeated grinding got me too bored to continue.
Some observations
Grind , grind and grind again, that's the secret to not get killed. Go back to locations explored already, do not rush for the next that will appear, you really need to get more levels.
Battles become longer and longer due to the enemies getting a ton more health as the game progress, be sure to "reposition" regularly to break the enemy guarding (extremely annoying game mechanic to me as the enemy is guarding nearly every turns) or it will take even longer, and only hit when they don't have their guard up.
Before getting in a new or a boss area, go fight again some enemies in previous locations, your goal is to have your most powerful "ultimate" ready most of the time you'll get into a new battle.
That gauge only increase , very slowly, so you'll have to hit a lot to get it filled, the 1st ultimate will be completely useless after some point (as at that point of the game the enemy have too much health to even notice its damage), so continue getting the gauge up with weak enemies until you get the higher version that deal absurdly high damage .
This way you'll be able to fight those silly bosses and be able to halve or more their gigantic amount of health in a single turn, lowering a bit the tedium of fighting them endlessly
Heal regularly, as the enemy have an "ultimate" or two gauge too (reposition usually helps to lower it) and can then deal high damage in a burst sometime, so don't get caught with low health when it happens.
Do not overlook the crafting, learn to control that minigame and you'll get some really good items that when you obtain them of really great quality will be better than what you'll find.
Weapons can only be crafted by the blacksmith, so don't hesitate to go give him your metal scrap when possible and hope he'll give you something good (depending on the game stage i guess) or at least that correspond to your weapon masteries.
The grinding part that is dominant in this game reminds me strongly of those candy box 1 and 2 , SanctuaryRPG is really a mix of many genre.
