I've made yet another attempt at a homebrew subclass. Im really trying to build my skills in this so I'd appreciate any constructive criticism or advice on it.
Rogue: Gambler
Cards and tricks are child's play. The real thrill is to gamble with your life. Living on the edge keeps your wits sharp and your blades sharper.
**Level 3**
*Bonus Offer*
While bloodied, your AC increases by 1.
*House Edge*
You have Proficiency in all Gaming Sets. You have advantage on deception rolls for cheating while using them.
*Rake*
When making a sneak attack, you can remove 1D6 from your sneak attack damage to use it to heal yourself instead. You can choose to remove an additional 1d6 to use in this way at level 9, 13, and 17. Once you use this ability an amount of times equal to your Dexterity modifier, you can't do so again until you finish a short or long rest.
**Level 9**
*Call*
When you use Uncanny dodge, you can instead choose to take the full damage and use the reaction to retaliate with an opportunity attack instead.
*Bluff*
As a reaction, immediately when you trigger a reaction from another creature, you have the benefits of 1 illusory duplicate as described under the the Mirror Image spell until the start of your next turn. Once you use this ability an amount of times equal to your Proficiency Bonus, you can't do so again until you finish a long rest. At level 13 and 17 you gain an additional illusory duplicate as described under the Mirror Image Spell. Each additional duplicate extends the duration of this ability by another turn.
**Level 13**
*Heads I win, Tails you lose*
At the start of initiative, Flip a coin. On heads you have no penalty to your next cunning strike effect. On tails, you gain an extra bonus action on your first turn.
**Level 17**
*All In*
Taunting fate your whole life has made you no stranger to death. You've learned to perfectly imitate it when it comes knocking.
When you make death saving throws, you do so with advantage but each success and failure counts as 2. You can't be the target of an attack during this time. During your turn, when you stabilize on your own without interference or assistance, you gain the the benefits of a short rest and are invisible for 1 minute. As long as you're invisible in this way, you leave behind a lifeless body double where you fell.
