Tips

Arguably the most useful trail spell as water is almost always very beneficial to you. Exceptions include making so much you drown in it, or washing away beneficial stains (like Berserkium).
With the Breathless perk, one strategy is to flood an entire biome using this modifier.
Synergizes well with all electrical effects, as long as you yourself have Electricity Immunity or Electricity perks.
Attach this to a wand to provide easy and readily available protection against being on fire or soaked in Toxic Sludge.
As all trails leave behind material over time, a faster projectile spell may be more useful to prevent flooding (unless that is what you want, in which case you should use a slower one).
Sets the Wet status for 720 frames (12 seconds) on enemies hit by affected projectiles, even if they do not actually get stained by the produced water, and even if water has been shifted to a different material. In combination with Critical on Wet (Water) Enemies, this guarantees critical hits.
