You know how the Swarm Seed works, right? Well, you no longer need to join the dark side. The light one just stole their cookie factory! Like the original Swarm Seed, this would not deal damage itself.

Swarm Seeds buff enemies by giving them defense (and attack?) ups to monsters and slowing down knights that walk over it. The light seed bomb would do the same, but supporting knights instead. It also spreads itself. Monsters could also target it and beat the Agni out of it, and no, this one would NOT be invicible. It actually would die and would get smaller by 1 size for every 1 monster/ld opponent attack it takes.

Op op op, right? So here's the catch. The seed would last as long as a Faust (4*) Self-curse in Proto set, and the bomber might only plant another once this period is over. If the seed dies during that period, the time penalty for seed-planting would be doubled for the floor. Killed once again? Triplified. One more? Fourtified. And so on, and so on. I am not a Book Worm, so excuse me if those words do not exist.

So, how do I get it, you may ask. Well, once reaching the Darkfire Citadel instance of The Sanctuary, the player would need:

-To have collected all SL sets.
-To have at least 1 of each SL material in their inventory.

Instead of a Maiden Tear, this bomb would appear. The entity that gave you Echo Stones would be now standing next to the weapon, and would have a small, purple block glowing in it's heart. The Swarm.

Upon interaction, the entity would say:

"Flee my dear Knight, flee from it. If it comes out to get you, use this bomb to defend yourself. I no longer have a reason to hold it back, now you collected everything from this... calm in the storm. But the storm wants to come in. Flee before it'll consume me, and flee before it'll consume you!"
After this interaction, the entity would disappear.

Design: Same as a 5* Shard bomb, entirely white. The smaller floating shards around it are replaced by small Sanctuary cubes.

So finally, the description.
"A strange seed made out of purity and light that fends off anything evil."
