- Offhand attacks can be made without making a mainhand attack with another light weapon first.
- Object interactions are unlimited. (can switch from bow, shoot, to dual weild - offhand attack, to sword and board, all in one round)
- Stealth does not require a roll if you are heavily obscured, and it is possible even when only lightly obscured, whereas in PHB you MUST be heavily obscured in order to even attempt to hide.
- Shove does not allow you to push people prone, and it has a much greater shoving distance.
- Falling prone on your turn ends your turn and no actions can be taken while prone.
- Enemies make saves vs hold person at the start of their turn, and can then take actions after. A huge nerf ot the spell.
- Invisibility does not allow you to target the enemy with single target attacks - in PHB invisiblity just gives you disadvantage, but unless they are hhiding you should still be aware of their location and be able to make attacks against them, so long as it is not a spell that requires you to see the opponent.
- Spells no longer use components, aside from verbal - which all spells now use.
- Invoke duplicity now serves as nothing but a distraction.
- Mirror image has been majorly nerfed to now provide +3 ac per duplicate, and you lose one of the clones each time an enemy misses you, rather than each time you are hit and the attack is deflected to a copy.
- Colour spray now works against a fixed number of hp liek the sleep spell.
- The sleep spell has a much shorter duration.
- Offhand attacks automatically grant your ability score modifier to damage.
- Thief gets an extra bonus action for its fast hands ability, as opposed to being able to use objects as a bonus action. And it can use this e xtra bonus action to make a second offhand attack.
- Thief gets resistance to falling damage instead of no penalty to climbing speed.
- Arcane trickster no longer gets mage hand + 2 cantrips, instead they just get 2 cantrips.
- The help action now restores a downed character to 1hp rather than providing advantage.
- Jumping now requires a bonus action, and has been tied to disengage,
- You cannot move through friendly spaces (unless you jump over them).
- False life now gives a flat 5 temporary hp, rather than 2d6 (a nerf)
- Dancing lights now requires concentration.
- No cover rules have been implemented (aside form full cover)
- Sacred flame ignores full cover.
- The GWM and sharpshooter feat have been combined - heavy crossbows now coutn as heavy weapons and work with great weapon master, but sharpshooter feat has been removed.
