Apologies for the delay in responding to your request, we are currently experiencing an extremely high volume of tickets. Thank you so much for your request and your patience with us!
For this concern, we would like to confirm that both a Resource Drop Chance and Mod Drop Chance booster will affect a different loot table from enemies. Basically, this means that a Resource Drop Chance booster will only affect the chance for resources to drop and won't affect the chances for mods. Conversely, a Mod Drop Chance booster, will not affect the chances for resources to drop like the Vitus Essence. Blueprint drop rates won't be affected by either booster.
Essentially, these boosters increase the chance for certain drops when enemies are killed, however, it does not guarantee a specific drop and will still be based on (increased) random chance.
Hopefully this has helped clear things up but if you have further questions, please feel free to submit your reply here.
Best regards,
Warframe Support Team

简易翻译:
很抱歉延迟响应您的请求，我们目前的门票数量非常多。非常感谢您的要求和对我们的耐心！
考虑到这个问题，我们认为资源掉落几率和Mod掉落几率提升会影响敌人不同的战利品表。这意味着一个资源掉率加成只会影响资源掉落几率，而不会影响掉落mod的几率。相对的，MOD掉率加成不会像生息精华一样影响资源的掉落几率。蓝图掉率不会受到任何加成影响。
从本质上讲，这些掉率加成物品增加了敌人被击杀时掉落某些物品的几率，但是，它并不保证特定掉落，仍然基于（增加的）随机几率。
希望这有助于澄清问题，但如果您有进一步的问题，请随时在此提交您的答复。
顺致敬意，
Warframe支持团队

主吧还有两个测试贴，搜mod掉率就行
