don't be discriminating peeps
here's what i recommend:
5 points into drain, 5 into the multiple targets, 1 into slow, and 4 into either SP drain or the stat bonus. when they finally uncap the levels, you can use that one point into whatever, and with the remaining 4 points, either put em all into hp bonus or put one into "conflagration". hp bonus because spear lanns get beat every which way.
due to the attack damage cap, just leave that ATT increase alone.
