But how the heck do you stay safe from a siren?
Right now, you should just kill them as fast as possible, as they are pretty fragile. But I would like to expand the usefulness of Willpowerand make it possible to resist siren's call with high Willpower, so that an enchanted helmet of indomitable will would be a good defense against them.
And mommo slimes seem to have gotten a lot stronger.
Nothing changed as far as strength of their acidic slime goes, AFAIK, they were always a nuisance.
