Cards and Power Growth
Overview
BGF supports a card-based power growth layer that can add build variety, replay value, and mid-run decision making.
Cards are useful when a client wants the player to become stronger over the course of a run without relying only on fixed equipment or permanent unlocks.
What Cards Can Do
Cards can provide:
- direct stat upgrades
- temporary buffs
- stronger boss-grade rewards
- triggered combat effects
- run-to-run build variety
Card Tiers And Offer Rules
BGF supports:
- regular card pools
- boss-grade card pools
- rarity levels
- weighted offer chances
- level-based availability rules
- pick limits per run
This gives a project control over when certain upgrades appear and how often they can be taken.
Types Of Power Growth
Cards can improve a run through stat changes such as:
- more health
- more damage
- more speed
- more stamina
- more shield
- stronger regeneration
This supports both simple numerical growth and more specialized builds.
Triggered Card Effects
BGF also supports cards with triggered effects, including effects that activate on events such as:
- primary attack use
- distance moved
- skill use
- hitting an enemy
- taking damage
Supported effect styles already include examples such as:
- missile spawns
- grenade throws
- lightning strikes
- projectile spawns
- timed buff application
This allows cards to shape play style, not only raw stats.
Why Clients May Want This
The card layer is especially useful for projects that want:
- replayability between runs
- build experimentation
- stronger reward moments
- a sense of momentum as a campaign or run develops
Practical Design Use
A client can use the card system to request design ideas such as:
- aggressive damage builds
- survival-focused shield and regeneration builds
- mobility-focused builds
- boss reward moments with more dramatic upgrade choices
Relationship To Other Systems
Cards work well alongside actors, campaigns, and equipment. In practice, this means a game can combine:
- character identity from actors
- long-term gear from items and equipment
- mid-run adaptation from cards
That combination gives BGF a strong progression toolkit for both action-heavy and story-driven games.
