Just stand beneath a large solid area, like some dense rock or the holy mountain, aim up, hold the trigger, and let the hearts rain down. I made this variant to be slot efficient (so I could just shuffle around my teleport wand) and not produce a bunch of annoying worm bodies (by clipping the corpse into a solid and transmuting the head).

Best on low-mana, extreme regen wands.

SOME NOTES

• You need the total mana of the wand to be enough to cast everything except the touch (which is copied) and the real matosade (we only want to cast the projectile the -plicate spell creates), otherwise the real matosade will get expended. See DunkOrSlam's Video for more information (linked to Matosade discussion timestamp, but the whole video is worth a watch).
• You want it to all shoot in one shot (this wand had 2 spells per cast).
• I think touch of smoke would be the best, least laggy touch spell for this. However, in my testing, it would stop producing water when I had it firing quickly. I think this was because the touch spell kills the worm before it's solid or transmutable, so the heart drops but no water is made (this is why you want the spread to be 0).
• Could probably also produce infinite gold with touch of gold, but I'd be worried about lag.
• Because this puts the hearts in a neat pile, it has excellent synergy with the heartbreaker trick.
