RG Tulsi looks good but don't multi-target healing abilities like hers work on a character-to-character basis? That is, Knight #1 rolls to see if they trigger the 25% chance to heal then Knight #2 rolls, then #3 rolls, etc. Still, even if that is the case then RG Tulsi's still a decent choice given her other abilities (15-60% attack power, 1.2x skill proc, +30% defense and -20% pest attack power).
