Equipment

You start with the following equipment, in addition to the equipment granted by your background:

• Omnitrix

At 1st level, you aquire the Omnitrix. The Omnitrix is a powerful and complex magical device, little is understood about how it works. When weilding an Omnitrix, it automatically attunes to the wearer and once put on it can only be removed by magical means. A person attempting to remove the Omnitrix (unattune to it) must make a Intellegence check according to your spell save/primary ability save DC (this is Wisdom by default) or the Omnitrix will try to defend itself and the wearer. If the person attempting to remove the Omnitrix fails the check, they take 2d6+2 force damage per class level, and are temporarily blinded by a flash of light. In addition, a failed check will automatically change the wearer randomly into one of their stored creatures.

Starting at 1st level, you may choose up to 10 monsters with a crof CR 1/4 to add to your Omnitrix.

Transforming

To transform into a creature, you must announce which of the stored creatures you want to transform into. If you pass a DC 14 Dexterity saving throw, you transform into the desired creature. If you fail, one is selected at random. When you transform into a creature you adopt all of the creature's statistics, however you keep your own wisdom ability score. If the wearer's hit points are greater than the creature's that you transform into, the extra carry over as temporary hit points. Transformations last for 1d6 minutes (at level 1). Once the duration ends the wearer cannot transform for 4d6 minutes (at level 1). You can only use this feature when in an non-transformed state unless you have the Master Combination feature. If your hit points drop to 0 while transformed, you return to your original form.

Starting at 1st level, you can scan the DNA of other creatures and store their genetic information it the Omnitrix. As an action, you man scan a creature who's DNA is not in the Omnitrix, forcing them to make a Constitution saving throw with a DC equal to 8 + your Wisdom modifier + your proficiency bonus. An unconscious or immobile creature automatically fails this check. Willing creatures can provide their DNA without making the check.

Scanning Cooldown

Once the Omnitrix has scanned in new DNA, this feature cannot be used until you complete a long rest. Immediately after a scan, the wearer cannot transform using the Omnitrix for 2d6 minutes while the Omnitrix processes the new DNA.

Accidental Scans

When you take damage in your non-transformed state, there is a possibility that the Omnitrix will automatically scan the creature's DNA. If the creature is currently not stored within the Omnitrix, roll a percentile dice, if you roll 10 or less the Omnitrix will automatically scan the creature.

At 2nd level you discover that the Omnitrix is capable of handling stronger creatures. At 2nd level the max creature CR is increased to 1. At 4th level it increases to CR 2. At 8th level it increases to CR 3. At 10th level it increases to CR 5. At 12th level it increases to CR 8. At 16th level it increases to CR 11. And at 20th level the CR increases to 15.

At 3rd level, you chose a Strand. Choose between Mutant or Ultimate, both detailed at the end of the class description. Your choice grants you features at 3rd and again at 9th, 11th, and 14th level.

At 3rd level, the Omnitrix upgrades and you reduce the cool-down period by 1d6 minutes. You decrease this time by an additional 1d6 at 9th and 13th level.

At 3rd level you become more familiar with the capabilities of the Omnitrix you discover new features about it. You may choose 1 feature to acquire from the list below. You acquire additional features at 6th, 11th, and 17th.

Each time you take this upgrade, you can choose one creature in the Omnitrix or Codon Stream and increase all of its ability scores by 1 when you transform into that creature.

Slimebiote

Unlocks the ability to take on aspects of creatures stored in the Omnitrix or the Codon Stream. You can use this feature once per day for each time you take this upgrade. You can opt to switch one of your ability scores (except Wisdom), or adopt a sense the creature has. If this requires the wearer to take on an aspect of the creature, they do so. Work with your DM for flavor ruling on this. This ability becomes your own.

When you reach 4th level, and again at 8th, 12th, 16th and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.
