In the Tactics readme, it even directly states some of that:

This component makes the Druid Grove quest (from Trademeet) just a bit more difficult (to the point where the poison or trying to walk around Kyland Lind actually almost become attractive). The swamp outside the grove is now replete with flavorful (but not actually difficult) druidic creatures (e.g., giant mushrooms, shambling mounds, wyverns, more trolls, earth elementals). The generic Shadow Druids are now half-decent tenth-level totemists who might actually scare you with an insect plague. The big change is Faldorn herself -- now she's truly "stronger than ever with the aid of this grove". Expect to be on the business end of some 7th level druid spells (e.g., creeping doom, nature's beauty, fire storm). Faldorn's claws strike like the Staff of Thunder and Lightning. [ This has the side effect of fixing that bug in Ease Multi-Stronghold that causes Faldorn to do nothing if you challenge her with a non-druid, but not the Ease Multi-Stronghold "feature" that prevents you from having Cernd do the fight for you.
