Okay, let's see. The user is asking about the level in RuneScape where you reach half the XP of the max level. The max level is 99, so they want to know at which level you have half of the total XP required for level 99. Looking at the provided book, there's a section called "Skills/Experience Table" that lists the XP needed for each level. The total XP for level 99 isn't directly listed, but I can calculate it by summing up all the XP needed from level 1 to 99. However, the user might just want the level where the cumulative XP is half of what's needed for 99. Wait, the Experience Table in the book shows the XP needed to reach each level and the difference from the previous level. For example, level 1 needs 0 XP, level 2 needs 83, so the difference is 83. To find the total XP for level 99, I need to sum all the "Experience needed to reach level" from 1 to 99. But the user is asking for the level where the XP is half of that total. Alternatively, maybe the user is referring to the XP required for level 99 being 130,344,310 (as per the last entry in the Experience Table). Let me check the last row in the table. The last entry is level 99 with 130,344,310 XP needed. So half of that would be 130,344,310 / 2 = 65,172,155 XP. Now, I need to find out which level has an XP requirement that's closest to 65,172,155. Let me go through the Experience Table entries. For example, level 60 is 27,374,208, level 70 is 73,762,700. Wait, 73 million is higher than 65 million. So between level 60 and 70. Let's check level 68: 60,503,308. Level 69: 66,805,100. That's very close to 65 million. So, the XP needed to reach level 69 is 66,805,100, which is just a bit over half of the XP needed for level 99. Therefore, the answer would be around level 69. However, the user might be looking for a general idea or a specific level mentioned in the book. The Experience Table doesn't have a direct midpoint level, but based on the data, level 69 is the closest. Alternatively, maybe the user is referring to the XP difference between levels, but the question is about the cumulative XP to reach a level. I need to make sure I'm interpreting the table correctly. The "Experience needed to reach level" column is the total XP required to reach that level. For level 99, it's 130,344,310. Half of that is 65,172,155. Looking at the table, level 69 requires 66,805,100 XP, which is just above half. So the answer is level 69. However, the user might not need an exact calculation but a general idea. Since the XP curve is exponential, the midpoint in terms of level isn't the same as the XP midpoint. But according to the data here, it's level 69. In Old School RuneScape, the total experience (XP) required to reach **Level 99** is **130,344,310 XP** (as listed in the "Skills/Experience Table" for Level 99). Half of this total XP is **65,172,155 XP**. From the XP table, the level closest to this midpoint is **Level 69**, which requires **66,805,100 XP** to reach. This is just slightly above half the total XP for Level 99. ### Key Points: - **Level 69** is the approximate level where your cumulative XP reaches half of what is needed for Level 99. - The XP curve is exponential, meaning the gap between levels grows as you progress. For example, Level 69 is closer to the XP total for Level 99 than you might expect based on the level number alone. This calculation assumes you are summing the total XP required to reach each level (not the difference between levels). If you need further clarification or details, let me know!
