Artifact charges and debuff applications
One large application does not necessarily remove more Artifact than a small one. If a target has one Artifact and the next card applies several turns of Weak as one event, that application is blocked. The extra Weak amount does not become multiple attempts to pass the remaining protection.
This is why upgrading the amount on a debuff card can fail to solve an Artifact problem. The deck may need another application, a different ordering of the available cards, or an effect that removes Artifact explicitly. Read the target’s current defenses before spending the large application the rest of the turn depends on.
Cards with multiple debuffs
Uppercut deals damage, applies Weak, then applies Vulnerable. Against a target with one Artifact, the earlier debuff can consume protection before the later debuff is attempted. That makes ordering inside the card relevant as well as ordering between cards. It does not mean the first debuff also lands.
Bouncing Flask makes repeated Poison applications to random enemies. With only one target, those applications can remove several Artifact stacks rather than behaving like one combined Poison amount. Against a group, targeting becomes uncertain: the applications may be split among enemies, so the same card cannot promise to strip one selected target completely.
Debuff sequencing
Suppose the turn needs Weak to survive an incoming attack, but the enemy still has Artifact. Playing your only Weak card first can spend its effect on protection and leave the damage unchanged. A different debuff or a potion may remove protection first, letting the defensive application land afterward.
The opposite priority can apply on a finishing turn. If Vulnerable enables lethal damage, preserve its application until the target is exposed. The damage strategy benefits only after the status is actually applied; a card that attempted Vulnerable is not equivalent to an enemy currently carrying it.
Expose and Artifact removal
Expose removes all Artifact and Block before applying Vulnerable. It therefore handles a different problem from simply applying a large amount of a debuff. Because the card Exhausts, plan its timing around the important target and turn rather than assuming it remains a repeatable source of Vulnerable throughout a long combat.
The choice also has an opportunity cost. An encounter with no important Artifact or Block may not require this particular answer. The point is to cover a real defensive layer, not to add every counter card to every deck.
Damage against Artifact
A Poison deck or Doom deck can lose several setup turns while removing protection. Keep usable defense and damage that can progress the fight during that interval. A potion saved for an awkward matchup may contribute more than another ideal-scenario payoff.
Do not confuse Artifact on an enemy with a promise that the player can obtain the same protection. Prepare from the actual player cards and relics available in this game and branch.
