Enlarge [two-actions] Spell 2

Concentrate Manipulate Polymorph
Source Player Core pg. 329
Range 30 feet; Targets 1 willing creature
Duration 5 minutes

Bolstered by magical power, the target grows to size Large. Its equipment grows with it but returns to natural size if removed. The creature is clumsy 1. Its reach increases by 5 feet (or by 10 feet if it started out Tiny), and it gains a +2 status bonus to damage rolls on melee Strikes. This spell has no effect on a Large or larger creature.

Heightened (4th) The creature instead grows to size Huge. The status bonus to melee damage is +4 and the creature's reach increases by 10 feet (or 15 feet if the creature started out Tiny). The spell has no effect on a Huge or larger creature.
Heightened (6th) Choose either the 2nd-rank or 4th-rank version of this spell and apply its effects to up to 10 willing creatures.

Invisibility [two-actions] Spell 2

Illusion Manipulate Subtle
Source Player Core pg. 339
Range touch; Targets 1 creature
Duration 10 minutes

Illusions bend light around the target, rendering it invisible. This makes it undetected to all creatures, though the creatures can attempt to find the target, making it hidden to them instead. If the target uses a hostile action, the spell ends after that hostile action is completed.

Paizo Clarification

Invisibility follows the rules of the invisible condition. The second sentence summarizes them but doesn't cover every instance, such as you being hidden to creatures observing you when you become invisible instead of being undetected to them.

Heightened (4th) The spell lasts 1 minute, but it doesn't end if the target uses a hostile action.

Harm [one-action] to [three-actions] Spell 1

Manipulate Void
Source Player Core pg. 334
Range varies; Targets 1 living creature or 1 willing undead creature

You channel void energy to harm the living or heal the undead. If the target is a living creature, you deal 1d8 void damage to it, and it gets a basic Fortitude save. If the target is a willing undead creature, you restore that amount of Hit Points. The number of actions you spend when Casting this Spell determines its targets, range, area, and other parameters.

[one-action] The spell has a range of touch.
[two-actions] (concentrate) The spell has a range of 30 feet. If you're healing an undead creature, increase the Hit Points restored by 8.
[three-actions] (concentrate) You disperse void energy in a 30-foot emanation. This targets all living and undead creatures in the area.

Heightened (+1) The amount of healing or damage increases by 1d8, and the extra healing for the 2-action version increases by 8.

Magic Weapon [two-actions] Spell 1

Legacy Content

Transmutation
Source Core Rulebook pg. 349
Cast [two-actions] somatic, verbal
Range touch; Targets 1 weapon that is unattended or wielded by you or a willing ally
Duration 1 minute

Cantrips

Detect Magic [two-actions] Cantrip 1

Cantrip Concentrate Detection Manipulate
Source Player Core pg. 323
Area 30-foot emanation

You send out a pulse that registers the presence of magic. You receive no information beyond the presence or absence of magic. You can choose to ignore magic you're fully aware of, such as the magic items and ongoing spells of you and your allies.

You detect illusion magic only if that magic's effect has a lower rank than the rank of your detect magic spell. However, items that have an illusion aura but aren't deceptive in appearance (such as an invisibility potion) typically are detected normally.

Heightened (3rd) You learn the rank or level of the most powerful magical effect the spell detects, as determined by the GM.
Heightened (4th) As 3rd rank, but you also pinpoint the source of the highest-rank magic. Like for an imprecise sense, you don't learn the exact location, but can narrow down the source to within a 5-foot cube (or the nearest if larger than that).

Shield [one-action] Cantrip 1

Cantrip Concentrate Force
Source Player Core pg. 356
Duration until the start of your next turn

You raise a magical shield of force. This counts as using the Raise a Shield action, giving you a +1 circumstance bonus to AC until the start of your next turn, but it doesn't require a hand to use.

While the spell is in effect, you can use the Shield Block reaction with your magic shield. The shield has Hardness 5. You can use the spell's reaction to reduce damage from any spell or magical effect, even if it doesn't deal physical damage. After you use Shield Block, the spell ends and you can't cast it again for 10 minutes.

Heightened (+2) The shield's Hardness increases by 5.
