Magically Charged

Instead of casting a spell using both an action and a bonus action, the warbeast uses either an action or a bonus action, depending on what is stated for casting time.
 

Mimicry

The warbeast can mimic simple sounds it has heard, such as whispering, a baby crying, or an animal chittering. A creature that hears the sounds can tell they are imitations with a successful DC 10 Wisdom (Insight) check.
 

Bird's Eye View

After performing a ten minute ritual with your warbeast, you can convert your conciousness into the warbeast's body, leaving your own body in a catatonic state. Any damage you take in this state will force your conciousness to return instantaneously. While your conciousness is within the warbeast, you see through its eyes, can use your class abilities as if they were your warbeasts, and use your warbeasts abilities as if they were your own. This lasts for up to an hour and can be used an amount of times per long rest equal to your constitution modifier.

Enhanced Magics

Once per long rest, if the casting time for a spell is more than 1 action, the warbeast can instead use an action and a bonus action to cast that spell. Additionally, you can add the warbeast's wisdom modifier to spell attacks made either by the warbeast or by you if you are in direct contact to the warbeast. This damage bonus is added on top of the the original spell attack bonus, it does not replace it. You can do this an amount of times equal to the warbeast's CON + PB.  

Expanded List

The Warbeast recalls past magics. The warbeast now has a spell list seperate to you, though it can still cast your spells. When the warbeast casts its own spells, it uses its WIS modifier instead of your CON modifier, though it still uses your PB. For every level you have above 3rd, the warbeast knows 1 spell from the druid spell list. These spells must be of equal level to your Alithald spells, and it uses your spell slots to cast these spells. Additionally, the warbeast knows an amount of druid cantrips equal to its WIS modifier.
