Hello everyone! When checking several bugs related to unit experience, I found a few interesting quirks in how shared xp system works. Since info about shared xp from <http://notdstarcraft.wikia.com/wiki/Marine_Experience> is outdated, I thought sharing this publicly would be beneficial to anyone curious. Every NOTD enemy has a "Shared Experience" behavior. The behavior triggers an effect called "Shared Experience Search Set" in the event of unit taking fatal damage. The Effect then invokes other effects in a tree like fashion, checking various conditions, until it finally gives a small fixed amount of xp. Here's a diagram: In simplified terms, it works like this. 1) someone kills a unit 2) the killed unit triggers a search for heroics in 7 radius of the killer, and entire map search for recon. 3) For each found unit, it launches a "switch" effect, that launches class specific effect that corresponds to unit class 4) The class effect gives a fixed set of xp, a very small amount as seen in the numbers 5) If the unit killed was slasher/agron/titan, bonus xp is given 8/15/20 respectively Key points: * There are no percentages of any kind. Everything is fixed values. It doesn't matter if the unit killed gives 1 or 100 xp, shared xp will always be the same. * Minions are not heroic, so they don't get shared xp. Recon drone or engy drone need to steal xp to level up. * There is very little difference between most classes. A flamer gets 0.55 xp per kill, a rifle gets 0.3 xp. For 1000 kills, the difference will be (0.55 - 0.3) * 1000 = 250 xp. * Shared xp is shared with self, so if marksman kills an agron, it gets 45 + 0.42 + 15 = 60.42 xp. Exceptions and Bugs: * Brain bugs do not share xp, because they lack "Shared Experience" behavior. * Minions like ivan, ogi, tech dog/crawler, fo minis, engy towers/probes/nexus/zoo, po projections have additional shared xp system. They give 100% of their kill xp, split evenly to close allied units that can have xp. So if 3 out of 8 players are close to black dog, when it makes an agron kill, each will receive 45 / 3 = 15 xp. Unexpectedly, the xp is also split with engy x1 or recon reaper drone. * Demo satchel acts normally, if demo kills a brainbug (45xp) with fo and reaper drone close, demo gets 45, while fo/reaper get nothing. If same brainbug was killed with Armageddon however, demo/fo/reaper get 15 xp respectively. If no units that can collect xp are close to Armageddon, no xp is given, not even to demo. * Commando nukes share xp appropriately, mono traps only give xp to commando. * Pets also share their xp with surrounding units, but unlike minions, they do take their portion of xp. So if a predator kills a stalker (10xp), with an assault close by, predator gets 5 and assault gets 5. * L3 has its own system too, with a behavior called "XP Share Suppression" and a trigger based share that doesn't seem to work. Hope this answers some questions about shared xp.
