About this mod
Makes arcane trickster a full caster with some new abilities and changes centered around magical ambush and more casting
- Permissions and credits
Arcane Trickster is now a full caster, and starts out with 3 cantrips and 4 spells known at level 3. Arcane Trickster gains a new spell each level and can choose to replace a known spell from the Wizards spell list.
Lvl 3

Pretty much Counterspell with a long rest cooldown that upon success restores a spell slot. Note that it will go on cooldown regardless of whether you succeed or fail, and if you already have the full number of spells ready for the level in question, then you won't get an extra spell on top of that (Like when wizards restores a spell slot).Also changed the colors of the spell effects so it doesn't look exactly like Counterspell (basically, cheap recolor).
Lvl 6
Moved down magical ambush to lvl 6.
Lvl 9

Helps Arcane Trickster to go first and to have a free magical ambush fueled spell at the start of combat.
General Changes
- Magical ambush now triggers when you are invisible as well (to work with invis spells, and Trickster's Initiative).
- Sneak attack now automatically triggers if attacking while invisible (if turned on in reactions). Previously, if autoattacking from invis the stealth attack wouldn't trigger.
Multiclassing
If you do decide to multiclass *wizard lvl 1 dip* then make sure to first start as a lvl 3 Arcane Trickster, otherwise you won't get all spell slots you are supposed to get. Afterwards, multiclassing works normally.
