So just for fun i decided, why not try this without a shield?
surprisingly, it was really fun to try and outmanouver and get behind enemies, so then i thought;
1. why not be able to move faster
2. why not be able to dodge more often
3. why not get a backstab bonus
just because this was actually pretty fun to do, of course this was just in the early missions with enemies like those skinny robots and those small lizards so i dont know how viable this would be against later enemies or bosses...
because using a shield is what you should do, and you should go on shieldless runs only for fun or challenge. you're not supposed to go shieldless.
