=== Rule 1 ===
The further you progress through floors in Onslaught, the higher level enemies will become. This seems straightforward on the surface, but you can end up with enemies far stronger than in [[Chaos|chaos 7]] difficulty on floors 30
=== Rule 2 ===
These are common prefixes, suffixes, and names that will appear on a lane and determine what spawns from it. [[Bosses]] are not affected by special spawning conditions.
The first category determines what type of non-[[Chaos|chaos]] monsters will spawn.
=== Fodder ===
[[Witherbeasts|Wither Beasts]] will spawn here.
The following will determine what [[Chaos|chaos]] monsters will spawn. The prefixes/suffixes/names must be listed in a lane in order for said monster to spawn:
=== Vanguard / -Guard ===
=== Frosty- ===
Any frost mobs will appear. This will only appear around floor 30 and beyond. The Yeti [[Incursions|incursion]] will introduce you to these mobs.
=== Lava- ===
[[Lava Guardians]] will spawn here. This also only appears
around floor 30+. If you are having trouble dealing with these guys, they can also be found in the Demon Lord [[Incursions|incursion]].
The third category contains names that appear in flyer lanes:
=== Dargons ===
[[Kobold Flier|Kobold Flyers]] will spawn and attempt to dive-bomb your defenses.
The last category has special names that heavily change spawning conditions for the lane. None of the names above will be combined with any of these names:
=== Floppy Arms and Pig Bois ===
=== Air Raid ===
Hence the name, this will only appear in flyer lanes. This causes all types of enemies to spawn - usually in a larger quantity than usual. Heavy anti-air is highly recommended, but careful not to spend too many Defense Units!
=== Orcish Horde ===
Any assortment of mobs can spawn here, but only if they're orcs. This ranges from [[Orcs|regular orcs]] to [[Cyborks]] to [[Berserker Orcs]]. The anti-orc or orc-boom [[Mods|servos]] are great counters for these lanes.
=== Dreadbones' Crew ===
=== Just Timmy ===
[[Timmy]] spawns multiple times. Just like with Game-Ogre, single-targeting defenses are great for handling this lane.
