Modification: Find Familiar, Find Steed, & Find Animal Companion

By default, these spells do not cause a summoned companion to have increasing statistics. Their statistics are equal to whatever the default beast's is.

These spells are now modified as such:

At Higher Levels. When you cast this spell using a spell slot at least 1 level higher or more, the summoned companion gains the following benefits.

Find Familiar.
Per spell level higher, your familiar gains a bonus HD. If your familiar would reach a HD total divisible by 4, you can add +2 to either a single ability score or +1 to two different ability scores. Each additional spell level requires an additional 50gp worth of charcoal, incense, and herbs.

Find Steed.
Per spell level higher, your steed gains two bonus HD. If your mount would reach a HD total divisible by 4, you can add +2 to either a single ability score or +1 to two different ability scores.
If you use a 4th level slot, your mount gains an additional 10 feet of movement.

Find Animal Companion.
Per spell level higher, your familiar gains a bonus HD. If your animal companion would reach a HD total divisible by 4, you can add +2 to either a single ability score or +1 to two different ability scores.
If you use a 3rd level slot, your animal companion may be of large size or smaller. In addition, your animal companion can be up to a challenge rating of 1/2.
If you use a 4th level slot, your animal companion can be up to a challenge rating of 3/4.
If you use a 5th level slot, your animal companion can be up to a challenge rating of 1.
An animal companion cannot have more HD than the slot level used to find it.

This spell is not needed due to the Ranger rework.
