I feel like I've complained about this before, but the Gryvian Techie on FIRST-14 is in a bit of a rough state. I believe that the focus with her is "your weapons will be severely hampered by her shields, so you need to use teasing." However, if you do not unequip your clothes, and don't start out with Ice Cold, you end up with an abysmally low hitrate with your teases, and when they do land it's somewhere around 12 lust build-up. It makes the Techie practically unbeatable when you start out if you don't know to strip down until you're completely naked (or if you don't take Ice Cold).
And this is the tutorial area, effectively, with her seemingly being designed to teach you to use teasing given the shield regen and its accompanying message. There's nothing, as far as I can tell, which tells new players "hey, before you walk around, you should actually start streaking," so instead, many new players will just end up getting beaten down without recorse. Hell, even if you're not new, if you just forget that the optimal strategy against her is to take up the nudist lifestyle, you'll still probably end up loosing to her.
The point is: The Gryvian Techie needs to be significantly weaker to teases, or at least be much easier to hit with them, because every bit of signposting around her is trying to say "don't attack, just tease," but you need to strip or take Ice Cold to actually effectively do it.
