How to get drops from spectators in the Arena? (Far Cry 4)

far-cry-4

In Shanath Arena, sometimes the spectators drop in items to help you fight. I've heard audio like

"I've got a lot of money on you. Take this and don't die"

then there are coloured smoke drops with weapons, ammo or health packs.

Shown above. The purple smoke on the right.

How do I get the spectators to give more drops? Is it the number of kills, accuracy, or points?

Best Answer

It's the number of points, which will depend on how you kill the enemies.

For the fight, Ajay receives points depending on how spectacular his killing blows are. He does not get any points if an enemy is killed by another enemy. A regular kill (human or animal) awards 10 points; a stealth kill, explosive kill or headshot awards 25; thrown knife kill or stealth heavy infantry kill awards 50. Even if Ajay dies, he adds these points to his total rank. For a spectacular kill (25 or more points), Ajay may get a drop from spectators, either a health syringe (green smoke), ammo (purple), weapon (blue) or explosives (orange). Weapon drops can contain a weapon that is otherwise unobtainable.

Takedowns, and especially chain takedowns will award the most points.
