I also fist-pumped in reaction to rogueknight333 wisely implementing "severe rest restrictions", without which the player can simply "rest spam" - that is, throw themselves recklessly into a fight, inflict massive damage (but also take lots in return), rest afterwards to heal themselves completely, then just repeat over and over until game's end. Or in the case of spell-casters, simply empty their spellbook on the hordes, rest to replenish spell slots, then repeat again and again - which has always been a huge problem with Vancian magic, at least since Baldur's Gate II, where it really got out of hand (resting was instant in BGII, optionally healed the player fully, and rarely resulted in ambushes - a weak deterrent in IE RPGs, anyway, since ambushing enemies were walk-overs. On-rest ambushes in Swordflight are resource-draining and punishing: players will realize very quickly that resting in dungeons seething with undead is a big no-no).
