Destiny Grenades

I want a plasma grenade. Duh.

Your "grenade" will be a secondary ability determined by your focus. Similar to supers, they will have a cooldown rate, but they will be weaker and their cooldown rate will be faster. Personally, I would like a grenade/ability that involves throwing a small, glowing dodecahedron that is slightly transparent, and after it impacts or stops rolling, it expands causing a medium amount of damage, and trapping weak enemies within the expanded object, also damaging them and any other enemies that are not trapped by the expansion or are near it. The damage will be weaker the further the enemy is from the object and the object will fade away over a period of ten seconds, decreasing in power as time goes on. I would also like a grenade that is a purple ball of energy that opens a glowing portal where it impacts. This portal should then generate multiple, slightly transparent chains that will attach to enemies, pulling them closer and dealing more damage as they get closer. This one will cause an explosion after its timer runs out.

proximity mines with primary explosion with secondary explosive shrapnel i would like

Ik that the warlock has an ability where they shoot out an orange grenade that looks much like the pulse grenade from halo 4, you can see it in the e3 reveal

The going theory is that each class has a grenade like ability.

Humans: something other than just plan old frag grenade. Alien: maybe even a antimatter grenade.
