Spellcasting Changes

Diamonds

Diamonds and diamond dust are rare resources in the world of Agathok. As a result, many spells can be incredibly difficult to cast, despite the individual possessing a tool like an Arcane Focus. This is understandable and intentional for spells that provide resurrection, or some other form of strong life preservation. However, for other spells, it is not. As such, some spells have had their material components altered to allow them to be easier to cast.
In these following spells, the diamond material component has simply been replaced with "any gem" worth of equal value:

• Chromatic Orb
• Gate
• Glyph of Warding
• Nondetection
• Stoneskin
• Symbol

Furthermore, the Reincarnate spell now requires, "an amount of diamond dust worth 1,000 GP, which the spell consumes", instead of its usual rare oils as a material component.

Spell Changes

Find Familiar

(Level 1 spell)
Familiars summoned with the spell cannot be equipped with items and any items they possess disappear after they’re gone.

Magic Missile

(Level 1 spell)
When rolling damage for Magic Missile, the dice are rolled for each dart separately, not once and applied to each dart.

Awaken

(Level 5 spell)
You can only have up to two awakened creatures or plants at a time with the Awaken spell, and it must be tracked by you. If a creature or plant stays awakened for 30 days, or dies, you no longer need to track it and may awaken something else.

Using Spell Scrolls

While holding an unfurled Spell Scroll, you can attempt to cast the spell on it without Material components, following the rules below. If you succeed, the spell is cast and the scroll crumbles to dust. If you fail or if the casting is otherwise interrupted, the scroll isn't lost. If you fail, you must wait at least 10 minutes before attempting again.
Same Spell List & Cast-able Level. If the spell is on your spell list and of a level you can Hard Cast, you automatically succeed in using the Spell Scroll.
Same Spell List. If the spell is on your spell list, but is of a higher level than you can Hard Cast, you must succeed an Intelligence (Arcana) check (DC = 10 + the spell's level).
Can Hard Cast. If the spell is not on your spell list, but you can Hard Cast level 1+ spells, you must succeed an Intelligence (Arcana) check (DC = 12 + the spell's level).
Non-Spellcaster. If you are unable to Hard Cast level 1+ spells, you can only cast the spell if it is of level 5 or lower, and you must succeed an Intelligence (Arcana) check (DC = 14 + double the spell's level). For all intents and purposes, you are using your Intelligence to cast the spell, if applicable.
