Still seems like bad design that there are areas that have unavoidable damage (if you're going for 100%), though.
This is the kind of attitude I'm talking about though! The one I have to surpress in myself! In fact, it really isn't bad design, it's just less common for videogames to be designed this way. It's *good* design, imo, because it forces us to strategise in situations where there is no 'wrong answer', and adds massive strategic depth.
It's tactically the equivalent of the following choice:
What do I need most, a phase device and a suit of armour, or 3 medikits?
Which is infinitely deeper than the more common videogame choice:
Shall I take damage, or not?
The first question's answer depends on what we already have, and what we need. It involves so many factors, build, challenge, difficulty, item drops, health, inventory, experience, progress... The depth in knowing the 'perfect way' to handle a situation is richest in a game where you're forced to make compromises. :)
For some reason I thought there was an Angelic Conqueror Damageless badge.
I'm not even sure I believe it's possible to do N! damageless without cheating.
