Here's a FAQ that includes the damage calculation stuff from the official Forum.
Just a few pointers, before you dive into it:
- There are three types of damage: Physical, Magic, and True. Physical and Magic are pretty clear, some abilities can deal true damage.
- All damage types are treated separately.
- The calculation is the same for all champions, but depends on the hitting champ and the one who was hit. However, each champion has different base values for armor/MR/damage/etc and different increments on level ups.
- The actual damage resulting from Phys/Mag damage depends on multiple things:
- the damage you currently dish out (what you see in your character info). This is made up as a simple sum of your base damage and any flat bonuses from items.
- your armor/MR reduction rate.
- your armor/magic penetration rate. These come in absolute values and percentages.
- your enemy's armor or magic resistance.

For Summoner's Rift (5v5)
Baron Nashor - 15:00 initial, 7:00 respawn after death
Dragon - 2:30 initial, 6:00 respawn after death
Lizard/Golem - 1:55 initial, 5:00 respawn after entire camp death
Wolf camp - 1:40 initial, 1:00 respawn after entire camp death
Wraith camp - 1:40 initial, 0:50 respawn after entire camp death
Small golem camp - 1:40 initial, 1:00 respawn after entire camp death
For Twisted Treeline (3v3)
Ebonmaw (Dragon) Buff - 4:40 initial, 5:00 respawn
Grez (Lizard) Buff - 2:10 initial, 4:00 respawn
Ghast/Rabid Wolf Buff - 1:55 initial, 3:00 respawn after entire camp death
All small camps - 1:40 initial, 1:15 respawn after entire camp death
Not sure if these values are 100% accurate for Twisted Treeline after the recent jungle remake. If anyone has specific info, feel free to comment/edit it in.
Special Notes:
The values listed for the Ghast/Rabid Wolf and Lizard/Golem initial spawn are 1:55 officially in the wiki, however this appears to vary by about 1s and in practice they're actually a bit closer to 1:54 on the in-game clock
As indicated, a camp of neutrals will not respawn if even one mob is left alive in that particular camp. The timer to respawn will not start until the last mob is killed. For example, if I kill the Blue Golem at exactly 3:00 but leave the small casters alive, the Blue Golem will not respawn at 8:00, but rather, 5:00 after whenever those two casters are killed.
Also, unlike HoN / DotA, neutral mobs will still respawn if there is something obstructing their spawn point (e.g. a ward, an object like Shaco's JitB or a Nidalee trap, a player, etc.)
Best Answer
You will still be revealed if you are spotted BEFORE you enter stealth
You will NOT be revealed if you are already stealthed (as said in the tooltip)
this was discussed in a forumpost and no patch affected it since then.
If you want to counter champions that rely on stealth (Akali, Shaco, ...) I recommend Oracle's Lens. It lasts longer, reveals wards and has a pretty low cooldown.
