I find myself getting my clocked cleaned a lot. Is there anyway to toughen this guy up? I'm always asking for help and on the floor, shields need to be twice what they are if you need them so much - even then they will be half of what you need. And why for God's sake would the tank be able to get two magic potions before two health potions?
And I would love to see more RPG elements, like being able to choose what you can make better, attacking, defense, that sort of thing.
I had a few rough patches earlier on with Caddoc and yeah the earlier shields can break a fair bit and I found myself shieldless a few times which is not a good situation to be in

. While his other weapon 'spells' are decent, I found myself almost exclusively using his Charge spell which is just incredible at pulverizing enemies/smashing their shields to bits (which can be good or bad if you need a new shield

). There is also an unlockable talent that improves your shield strength. I think the potion unlocks are from doing certain things (can't quite recall atm) so I don't think it's a guarantee that you will unlock 2 mana potions before 2 health potions. Regardless, the Weapon "Spells" are just as useful for Caddoc as they are E'lara.
His other 2 weapon spells (the whirlwind/levitate and his "rage" one) are okay, but I think you will find his charge spell much more satisfying for making Caddoc a badass. Once you get to rank 3 of that charge, you can seriously lay down the pain. Don't use it to charge across the battlefield, but sprint/roll/block your way relatively near to your enemies then turn them to pulp with a charge

. Early on I tried to play conservative with the mana use but the enemies seem to drop the potions quite a bit, encouraging their use.
The battle charge spells are nice for buffing your ally and situationally useful on certain fights, but one problem with using them with Caddoc is he is supposed to be up close and in the thick of things and when you cast those spells you put away your weapon and shield which leaves you extremely vulnerable.
I'd also recommend practicing your blocking and paying attention to how many attacks your enemies do before leaving themselves open. They will frequently double attack (some perform rather lengthy attack chains) and trying to squeeze off an attack may do some damage to your enemy but you will also lose a good chunk of health as well.
