The concept of InflationRPG is getting a lot of Experience per kill. So much in fact, that most of the time, you will gain dozens of levels per kill. The goal of the game isn't to get to a certain level, but to get to the highest level you can before running out of material.
For each gained level, you are granted 4 Stat Points (SP). These can be applied to the following categories:
HP: (Starting Value: 100, +5 per Stat Point) Hit Points.
ATK: (Starting Value: 10, +3 per Stat Point) Attack Power, the primary damage attribute.
DEF: (Starting Value: 10, +3 per Stat Point) Defense is a percentage modifier on enemy's damage. It is impossible to attain 100% Defense, regardless of how high your defense is.
AGI: (Starting Value: 5, +2 per Stat Point) Agility slightly increases your chances to generate Combos and Critical Hits.
LUC: (Starting Value: 1, +1 per Stat Point) Luck is the base value to increase Gold and DropRate. The more LUC you have, the more you generate Gold per kill, and have a higher chance to drop loot (DropRate is also modified by the Area level, and thus, a higher level area requires a higher amount of LUC to increase an item's DropRate). LUC also slightly increases your Critical Rate.
For all modifiers (except HP), they are modified by an enemy's Point Value, which means you need more Stat Points to keep up with how high enemies will get.
Character Selection is arranged in a 4x4 grid, with 16 characters to choose. Each Character has different stat multipliers which will be upgraded after each BaseLv up and CharacterLv up. Those stat multipliers appear as Bonus Stats in game, and their efficiency depends on which character you chose:
Characters towards the North (Up) will acquire up to a 2ATK (Attack Power) stat multiplier.
Characters towards the East (Right) will acquire up to a 2LUC (Luck) stat multiplier.
Characters towards the South (Down) will acquire up to a 2DEF (Defense) stat multiplier.
Characters towards the West (Left) will acquire up to a 2AGI (Agility) stat multiplier.
Characters closer to the center will acquire up to a 2HP (Hit Points) stat multiplier.
For example: the Grey-Haired Hero (Second Char on the top) has 1HP, 2ATK and 1AGI multipliers.
Base Levels are granted by killing Bosses. The first time you kill a boss from the list below, you are given one Base Level (Called "Base Abilities" in the Character Select Screen). These are the only 8 bosses that will grant you a Base Level upon their first death, other bosses won't, and you can't receive more BaseLvups from a boss you already killed for it. BaseLevel is used combined with CharacterLevel to calculate the Bonus Stats Multipliers the character you selected has. For more information on BaseLevel and stats, check out Player Values.
Base Lv1: Jousting Fox (Lv710 BOSS), located North of starting area.
CharacterLevel is the second Bonus Stats Multiplier, that gives you additional stats when you spend Stat Points. Those Bonus Stats applies to gems too: an HP+ gem on a HP character grants more HP than equiped to a pure ATK/AGI character. CharacterLevels are reached upon collecting Character Experience: when you finish a game, your used character will receive 1 Character Experience for each level acquired by killing monsters. If your character hits the following XP thresholds, your character is granted a CharacterLevel up!
