IDEA TIME
what if there was a tier 1 explosive, 'dynamite', that came with 4 shots: each toss threw somewhat sticky (think HE grenade-style) dynamite that exploded with roughly half the radius of a conc grenade and with about 60% of the damage output, but could be thrown in clusters with right click
and when i say 'clusters' i mean '3 or 4 sticks of dynamite at once with random shotgun-style spread'
it's tier 2 equivalent of course would be a pack of 8 sticks instead of 4
