English Version: Game speed will be doubled. Tap the item while in a battle to toggle it ON or OFF
Japanese Version: 戦闘スピードが2倍速になります
Cost: 50 Cat Food (25 during the sale event) for 9 items; in the 3DS version, 1 Speed Up costs 1 Cat Food.
Usage: A Speed Up can be used to boost the speed of battle (1.25%), for faster income generation, Cat Units' cooldown and enemy spawn rate, and so on. Can't be used for "speedrun" purposes (timed score will deplete twice as fast as well), however it can be used to beat long stages like Absolute Defence or Flappy Cat faster, or just to grind faster. Unlimited supply for Catclaw Dojo stages, applies for all other stages if the Officer's Club Gold Pass is purchased (30 days). Note that after V8.4, Speed Ups are the only items that carry over to Continuation Stages.
English Version: Treasure acquisition will be 100%. You will definitely get best treasure if you win the battle.
Japanese Version: お宝出現率アップ！
Cost: 90 Cat Food (45 during the sale event) for 2 items; in the 3DS version, 1 Treasure Radar costs 3 Cat Food.
Usage: Treasure Radars can be used to get Superior Treasures so the player can complete the Main Chapters quick, and/or get the Treasure buffs faster. In Legend Stages, it can be used to get cat units for hard stages when clearing it for the first time, like The Great Escaper, Cyclone Stages, and so on. Useless for stages with guaranteed drops and those with the single drop or Superior Treasure already obtained.
English Version: Worker Cat starts at the highest level.
Japanese Version: 戦闘開始時から働きネコのレベルが
Cost: 150 Cat Food (75 during the sale event) for 7 items; in the 3DS version, 1 Rich Cat costs 2 Cat Food.
Usage: The Rich Cat is very effective in hard stages; the player can save money for expensive Cat Units, instead of upgrading the Worker Cat. Generally useless on long stages or those that spam weak money givers as you'll most likely get a level 8 Worker Cat anyways. The Rich Cat is most effective when used on short stages or stages with a really difficult start. Has priority over Worker Start Level UP Combos.
English Version: Cat CPU will control your base and fight for you. Don't expect much.
Japanese Version: ネコ型CPUが戦闘をやってくれます
Cost: 180 Cat Food (90 during the sale event) for 20 items; in 3DS version, 1 Cat CPU costs 1 Cat Food.
Usage: The player can use this item to spawn units immediately when their recharge is complete, which might make all the difference on tough stages. Be warned though, it can act differently when low on money, can fire the Cat Cannon by itself, can upgrade the Worker Cat by itself, and can go completely AFK, all of which can foil strategies. The Catclaw Dojo grants unlimited usage.
English Version: Receive 1.5 times more experience than usual upon stage clear.
Japanese Version: 戦闘終了後に得られる経験値が
Cost: 300 Cat Food (150 during the sale event) for 5 items; in the 3DS version, 1 Cat Jobs costs 1 Cat Food.
Usage: This item is very effective in stages with high XP drops, such as XP Stages or XP Megablitz. Cat Jobs, however, won't increase the XP bonus from treasures. Extremely useful in XP Colosseum and Merciless XP. Not recommended for stages with low XP rewards.
English Version: Cat Sniper provides cover fire and push back enemies. Attack power is proportional to your cat Base's health.
Japanese Version: スナイパーが援護射撃をしてくれます
Cost: 90 Cat Food (45 during the sale event) for 3 items; In the 3DS version, 1 Sniper Cat costs 2 Cat Food.
Usage: Use Sniper the Cat to keep enemies at a distance (particularly bosses) from powerful cats, and to get rid of weak enemies, so your heavy hitters can deliver damage where it counts. It doesn't do much damage mid-game and beyond. Can't harm the enemy base. Attack power is 0.5% of the Cat Base's health and knocks enemies back (doesn't apply for those with Knockback Immunity or with active Barriers). Useful for stalling bosses and interrupting their attack animations.
