5th Edition Core Set with Dice Roller {Shyathlis}

• The two-axis alignment system introduced in earlier editions returns, increasing the total alignments to 9 with the introduction of a 10th 'monster' alignment of unaligned.
• Actions are now more dependent on checks made with the six core abilities with skills taking a more supportive role.
• Saving throws are reworked to be situational checks based on the six core abilities instead of generic d20 rolls.
• The "Advantage/Disadvantage" mechanic was introduced, streamlining conditional and situational modifiers to a simpler mechanic: rolling two d20s for a situation and taking the higher of the two for "advantage" and the lower of the two for "disadvantage" and cancelling each other out when both apply.
• Skills, weapons, items, saving throws and other things that a character is trained in (proficient) now all use a single proficiency bonus that increases as level increases.
• Multiple defense values have been removed, returning to a single defense value of Armor Class and using more traditional saving throws.
• Action Points have been removed entirely. The first "Unearthed Arcana" article reintroduced Action Points in their Eberron format (along with many other Eberron campaign standards).
• The Death Saving Throw system has been changed; 3 successes results in a stabilization and 3 failures results in death.
• The power system of 4th edition has been removed, replacing them with more traditional class features that are gained as characters level.
• Each spell-casting class uses a unique system to cast their spells, with wizards and clerics returning to a slightly modified version of the spell preparation system of previous editions.
• Characters are allowed a single action and movement in their turn with the ability to break up their movement with their action.
• Healing Surges are replaced by Hit Dice, requiring a character to roll a hit die during a short rest instead of healing a flat rate of hit points.
• The time of a short rest is increased from 5 minutes to a full hour of light activity.
• "Bloodied" is no longer a condition.
• Multiclassing is reminiscent of 3rd edition. When a character levels, they can choose to instead add new levels of a different class and gain some of the features of that class.
• Most major races (and subraces) and classes are now included in the main Player's Handbook volume instead of being spread throughout multiple volumes.
• Feats are now optional features that can be taken instead of core ability score increases and are reworked to be occasional major upgrades instead of frequent minor upgrades.
• Character and monster average hit point values are lower resulting in combat situations that are resolved more quickly.
