Shared Senses. Uses your saving throw modifiers and you can see through it's eyes and communicate with it telepathically as long as it is within a mile.

Shared Growth (Level 6). The companion benefits from your combat Feats. If you have a feat that grants a benefit to weapon or spell attacks (e.g., Savage Attacker, Elemental Adept), it applies to the companion's attacks. If you have a feat that increases movement or saving throws (e.g., Mobile, Resilient), the companion gains those benefits. It cannot cast spells.

Personality Matrix (Level 6). The companion has one of the following traits based on its chosen personality (chosen when you finish a Long Rest):
Timid: The companion’s movement does not provoke Opportunity Attacks.
Protective: The companion gains a +2 bonus to its Armor Class.
Aggressive: The companion has Advantage on attack rolls if at least one of its allies (including you) is within 5 feet of the target and isn't incapacitated.

• Scaling: At druid level 10, the damage increases to 3d8 + your Wisdom modifier + your PB.
• Damage Type: Choose Acid, Cold, Fire, Lightning, Poison, or Thunder when you summon the companion.

Aggressive Strike (Level 10, Aggressive Only). The companion makes one Elemental Strike attack. On a hit, this specific attack deals 1d8 + your Wisdom modifier damage (instead of its standard scaling damage).

Cower & Bolt (Level 10, Timid Only). The companion takes the Dash or Dodge action.

Goading Roar (Level 10, Protective Only). The companion targets a creature it can see within 30 feet. The target must succeed on a Wisdom saving throw against your Spell Save DC. On a failure, the target has Disadvantage on attack rolls against targets other than the companion until the start of the companion's next turn.

Land: Topple (Level 3). When a creature within 5 feet of the companion attacks an ally, or when a creature provokes an Opportunity Attack from it, the companion can make an Elemental Strike. If it hits, the target must succeed on a Strength saving throw against your Spell Save DC or gain the Prone condition.

Sea: Sea Shell (Level 3). When the companion is targeted by a melee attack, it can increase its AC by 2 until the start of its next turn. If the triggering attack misses, the attacker takes damage equal to 2d8 + your Wisdom modifier (Chosen Damage Type).

Sky: Buffet (Level 3). When a creature moves within 5 feet of the companion, or when a creature within 5 feet attacks an ally, the companion can use its reaction to flap its wings violently. The target must succeed on a Strength saving throw against your Spell Save DC or be pushed 10 feet away.

Apex Mastery (Level 14). The companion can take up to two reactions per round. It unlocks one of the following ultimate reactions based on its form:

• Land (Pounce): If an enemy ends its movement within 50 feet of the companion, it can move up to its speed toward that enemy and make one Elemental Strike. If it hits, the target is automatically knocked Prone.
• Sea (Riptide): When a creature within 30 feet moves away from the companion or attacks an ally, the companion forces it to make a Strength saving throw against your Spell Save DC. On a failure, its speed becomes 0 until the end of the turn, and it is pulled up to 15 feet directly toward the companion.
• Sky (Cyclone Dive): When a creature provokes an opportunity attack from the companion, it can attempt to Grapple the target using your Spell Save DC. If successful, the companion can immediately fly up to half its fly speed vertically into the air, carrying the target with it.
