Some good abilities to look for:

Damage taken from small pests -50% (Examples: Toad Lily, Japanese Iris)
Heal on Pest Node (Examples: Edelweiss (current revival event unit), Leucocoryne)
Enemy Attack Down (Examples: Cherry Sage, Dahlia)
Team Skill Activation Rate Up (Examples: Justicia, Cymbidium)

Dodge chance (Examples: Waterlily, Setaria)
Counter Chance (Examples: Rose, Snapdragon)

Last two are less great but still solid. Failing these, Attack Up > Defense Up (unless you have a Counter-heavy group or combo Defense Up with Enemy Attack Down)

Pest nodes won't be as plentiful going forward, so those first two shouldn't be a priority. The rest of those abilities combine well with lifesteal attacks.

Pest nodes are less plentiful in later maps? Good to know, thanks.

And yes, stacking Enemy Attack Down + Skill Rate Up + Counter + Life Drain + Defense Up... dream combo right there
...Fat chance of any girl having 3 or 4 of those (base ability, evo ability, bloomed ability and skill). They'd be damn near immortal lol.

Pest nodes aren't, but enemies hit harder, so attack down, evade, and healing fountain units become more valuable.

Lavender in particular is godly for her 3x healing passive.

Reduce Dmg from Flies is still great since the dmg of them is fixed by the map, have to look at that more correctly to confirm it.

Healing on pest node is worse since most of them are placed in such a way that you won't really get something out of it. Edelweiss was awesome in the beginning, since everyone was scraping some Golds here and there and 12-5 was just a tunneling through pest nodes. Slice Gacha made her alomst obsolete though.

In all honesty, after getting 20 Event Girls, even exluding the original 3, you have pretty much won the game. Because at that point you can still make out enough by equipment and solar Blasting. Gacha Golds and Rainbows are overcompensating but nice to have if you plan on building a single squad for an RB and see how much you can do with 1 Point.
